FIELD

The present disclosure relates generally to computer user interfaces,and more specifically to techniques for managing spatial audio.

BACKGROUND

Humans can locate sounds in three dimensions (above and below, front andrear, and side to side). Different techniques can be used to modifyaudio such that a listener perceives the audio that a device creates ascoming from a particular point in space.

BRIEF SUMMARY

Some techniques for managing spatial audio using electronic devices,however, are generally cumbersome and inefficient. For example, sometechniques do not provide users with contextual awareness of the stateof the electronic device through spatial management of audio. Foranother example, some existing techniques use a complex andtime-consuming user interface, which may include multiple key presses orkeystrokes. Existing techniques require more time than necessary,wasting user time and device energy. This latter consideration isparticularly important in battery-operated devices. Further, existingaudio techniques to not sufficiently help users navigate graphical userinterfaces.

Accordingly, the present technique provides electronic devices withfaster, more efficient methods and interfaces for managing spatialaudio. Such methods and interfaces optionally complement or replaceother methods for managing spatial audio. Such methods and interfacesreduce the cognitive burden on a user and produce a more efficienthuman-machine interface. For battery-operated computing devices, suchmethods and interfaces conserve power and increase the time betweenbattery charges.

Although the following description uses terms “first,” “second,” etc. todescribe various elements, these elements should not be limited by theterms. These terms are only used to distinguish one element fromanother. For example, a first touch could be termed a second touch, and,similarly, a second touch could be termed a first touch, withoutdeparting from the scope of the various described embodiments. The firsttouch and the second touch are both touches, but they are not the sametouch.

The terminology used in the description of the various describedembodiments herein is for the purpose of describing particularembodiments only and is not intended to be limiting. As used in thedescription of the various described embodiments and the appendedclaims, the singular forms “a,” “an,” and “the” are intended to includethe plural forms as well, unless the context clearly indicatesotherwise. It will also be understood that the term “and/or” as usedherein refers to and encompasses any and all possible combinations ofone or more of the associated listed items. It will be furtherunderstood that the terms “includes,” “including,” “comprises,” and/or“comprising,” when used in this specification, specify the presence ofstated features, integers, steps, operations, elements, and/orcomponents, but do not preclude the presence or addition of one or moreother features, integers, steps, operations, elements, components,and/or groups thereof.

The term “if” is, optionally, construed to mean “when” or “upon” or “inresponse to determining” or “in response to detecting,” depending on thecontext. Similarly, the phrase “if it is determined” or “if [a statedcondition or event] is detected” is, optionally, construed to mean “upondetermining” or “in response to determining” or “upon detecting [thestated condition or event]” or “in response to detecting [the statedcondition or event],” depending on the context.

Embodiments of electronic devices, user interfaces for such devices, andassociated processes for using such devices are described. In someembodiments, the device is a portable communications device, such as amobile telephone, that also contains other functions, such as PDA and/ormusic player functions. Exemplary embodiments of portable multifunctiondevices include, without limitation, the iPhone®, iPod Touch®, and iPad®devices from Apple Inc. of Cupertino, Calif. Other portable electronicdevices, such as laptops or tablet computers with touch-sensitivesurfaces (e.g., touch screen displays and/or touchpads), are,optionally, used. It should also be understood that, in someembodiments, the device is not a portable communications device, but isa desktop computer with a touch-sensitive surface (e.g., a touch screendisplay and/or a touchpad).

In the discussion that follows, an electronic device that includes adisplay and a touch-sensitive surface is described. It should beunderstood, however, that the electronic device optionally includes oneor more other physical user-interface devices, such as a physicalkeyboard, a mouse, and/or a joystick.

The device typically supports a variety of applications, such as one ormore of the following: a drawing application, a presentationapplication, a word processing application, a website creationapplication, a disk authoring application, a spreadsheet application, agaming application, a telephone application, a video conferencingapplication, an e-mail application, an instant messaging application, aworkout support application, a photo management application, a digitalcamera application, a digital video camera application, a web browsingapplication, a digital music player application, and/or a digital videoplayer application.

The various applications that are executed on the device optionally useat least one common physical user-interface device, such as thetouch-sensitive surface. One or more functions of the touch-sensitivesurface as well as corresponding information displayed on the deviceare, optionally, adjusted and/or varied from one application to the nextand/or within a respective application. In this way, a common physicalarchitecture (such as the touch-sensitive surface) of the deviceoptionally supports the variety of applications with user interfacesthat are intuitive and transparent to the user.

Attention is now directed toward embodiments of portable devices withtouch-sensitive displays. FIG. 1A is a block diagram illustratingportable multifunction device 100 with touch-sensitive display system112 in accordance with some embodiments. Touch-sensitive display 112 issometimes called a “touch screen” for convenience and is sometimes knownas or called a “touch-sensitive display system.” Device 100 includesmemory 102 (which optionally includes one or more computer-readablestorage mediums), memory controller 122, one or more processing units(CPUs) 120, peripherals interface 118, RF circuitry 108, audio circuitry110, speaker 111, microphone 113, input/output (I/O) subsystem 106,other input control devices 116, and external port 124. Device 100optionally includes one or more optical sensors 164. Device 100optionally includes one or more contact intensity sensors 165 fordetecting intensity of contacts on device 100 (e.g., a touch-sensitivesurface such as touch-sensitive display system 112 of device 100).Device 100 optionally includes one or more tactile output generators 167for generating tactile outputs on device 100 (e.g., generating tactileoutputs on a touch-sensitive surface such as touch-sensitive displaysystem 112 of device 100 or touchpad 355 of device 300). Thesecomponents optionally communicate over one or more communication busesor signal lines 103.

As used in the specification and claims, the term “intensity” of acontact on a touch-sensitive surface refers to the force or pressure(force per unit area) of a contact (e.g., a finger contact) on thetouch-sensitive surface, or to a substitute (proxy) for the force orpressure of a contact on the touch-sensitive surface. The intensity of acontact has a range of values that includes at least four distinctvalues and more typically includes hundreds of distinct values (e.g., atleast 256). Intensity of a contact is, optionally, determined (ormeasured) using various approaches and various sensors or combinationsof sensors. For example, one or more force sensors underneath oradjacent to the touch-sensitive surface are, optionally, used to measureforce at various points on the touch-sensitive surface. In someimplementations, force measurements from multiple force sensors arecombined (e.g., a weighted average) to determine an estimated force of acontact. Similarly, a pressure-sensitive tip of a stylus is, optionally,used to determine a pressure of the stylus on the touch-sensitivesurface. Alternatively, the size of the contact area detected on thetouch-sensitive surface and/or changes thereto, the capacitance of thetouch-sensitive surface proximate to the contact and/or changes thereto,and/or the resistance of the touch-sensitive surface proximate to thecontact and/or changes thereto are, optionally, used as a substitute forthe force or pressure of the contact on the touch-sensitive surface. Insome implementations, the substitute measurements for contact force orpressure are used directly to determine whether an intensity thresholdhas been exceeded (e.g., the intensity threshold is described in unitscorresponding to the substitute measurements). In some implementations,the substitute measurements for contact force or pressure are convertedto an estimated force or pressure, and the estimated force or pressureis used to determine whether an intensity threshold has been exceeded(e.g., the intensity threshold is a pressure threshold measured in unitsof pressure). Using the intensity of a contact as an attribute of a userinput allows for user access to additional device functionality that is,in some circumstances, otherwise not be accessible by the user on areduced-size device with limited real estate for displaying affordances(e.g., on a touch-sensitive display) and/or receiving user input (e.g.,via a touch-sensitive display, a touch-sensitive surface, or aphysical/mechanical control such as a knob or a button).

As used in the specification and claims, the term “tactile output”refers to physical displacement of a device relative to a previousposition of the device, physical displacement of a component (e.g., atouch-sensitive surface) of a device relative to another component(e.g., housing) of the device, or displacement of the component relativeto a center of mass of the device that will be detected by a user withthe user's sense of touch. For example, in situations where the deviceor the component of the device is in contact with a surface of a userthat is sensitive to touch (e.g., a finger, palm, or other part of auser's hand), the tactile output generated by the physical displacementwill be interpreted by the user as a tactile sensation corresponding toa perceived change in physical characteristics of the device or thecomponent of the device. For example, movement of a touch-sensitivesurface (e.g., a touch-sensitive display or trackpad) is, optionally,interpreted by the user as a “down click” or “up click” of a physicalactuator button. In some cases, a user will feel a tactile sensationsuch as an “down click” or “up click” even when there is no movement ofa physical actuator button associated with the touch-sensitive surfacethat is physically pressed (e.g., displaced) by the user's movements. Asanother example, movement of the touch-sensitive surface is, optionally,interpreted or sensed by the user as “roughness” of the touch-sensitivesurface, even when there is no change in smoothness of thetouch-sensitive surface. While such interpretations of touch by a userwill be subject to the individualized sensory perceptions of the user,there are many sensory perceptions of touch that are common to a largemajority of users. Thus, when a tactile output is described ascorresponding to a particular sensory perception of a user (e.g., an “upclick,” a “down click,” “roughness”), unless otherwise stated, thegenerated tactile output corresponds to physical displacement of thedevice or a component thereof that will generate the described sensoryperception for a typical (or average) user.

A quick press of the push button optionally disengages a lock of touchscreen 112 or optionally begins a process that uses gestures on thetouch screen to unlock the device, as described in U.S. patentapplication Ser. No. 11/322,549, “Unlocking a Device by PerformingGestures on an Unlock Image,” filed Dec. 23, 2005, U.S. Pat. No.7,657,849, which is hereby incorporated by reference in its entirety. Alonger press of the push button (e.g., 206) optionally turns power todevice 100 on or off. The functionality of one or more of the buttonsare, optionally, user-customizable. Touch screen 112 is used toimplement virtual or soft buttons and one or more soft keyboards.

Touch-sensitive display 112 provides an input interface and an outputinterface between the device and a user. Display controller 156 receivesand/or sends electrical signals from/to touch screen 112. Touch screen112 displays visual output to the user. The visual output optionallyincludes graphics, text, icons, video, and any combination thereof(collectively termed “graphics”). In some embodiments, some or all ofthe visual output optionally corresponds to user-interface objects.

Touch screen 112 has a touch-sensitive surface, sensor, or set ofsensors that accepts input from the user based on haptic and/or tactilecontact. Touch screen 112 and display controller 156 (along with anyassociated modules and/or sets of instructions in memory 102) detectcontact (and any movement or breaking of the contact) on touch screen112 and convert the detected contact into interaction withuser-interface objects (e.g., one or more soft keys, icons, web pages,or images) that are displayed on touch screen 112. In an exemplaryembodiment, a point of contact between touch screen 112 and the usercorresponds to a finger of the user.

Touch screen 112 optionally uses LCD (liquid crystal display)technology, LPD (light emitting polymer display) technology, or LED(light emitting diode) technology, although other display technologiesare used in other embodiments. Touch screen 112 and display controller156 optionally detect contact and any movement or breaking thereof usingany of a plurality of touch sensing technologies now known or laterdeveloped, including but not limited to capacitive, resistive, infrared,and surface acoustic wave technologies, as well as other proximitysensor arrays or other elements for determining one or more points ofcontact with touch screen 112.

A touch-sensitive display in some embodiments of touch screen 112 is,optionally, analogous to the multi-touch sensitive touchpads describedin the following U.S. Pat. No. 6,323,846 (Westerman et al.), U.S. Pat.No. 6,570,557 (Westerman et al.), and/or U.S. Pat. No. 6,677,932(Westerman), and/or U.S. Patent Publication 2002/0015024A1, each ofwhich is hereby incorporated by reference in its entirety. However,touch screen 112 displays visual output from device 100, whereastouch-sensitive touchpads do not provide visual output.

A touch-sensitive display in some embodiments of touch screen 112 isdescribed in the following applications: (1) U.S. patent applicationSer. No. 11/381,313, “Multipoint Touch Surface Controller,” filed May 2,2006; (2) U.S. patent application Ser. No. 10/840,862, “MultipointTouchscreen,” filed May 6, 2004; (3) U.S. patent application Ser.

No. 11/228,700, “Operation Of A Computer With A TouchScreen Interface,” filed Sep. 16, 2005; (8) U.S. patent application Ser.No. 11/228,737, “Activating Virtual Keys Of A Touch-Screen VirtualKeyboard,” filed Sep. 16, 2005; and (9) U.S. patent application Ser. No.11/367,749, “Multi-Functional Hand-Held Device,” filed Mar. 3, 2006. Allof these applications are incorporated by reference herein in theirentirety.

Touch screen 112 optionally has a video resolution in excess of 100 dpi.In some embodiments, the touch screen has a video resolution ofapproximately 160 dpi. The user optionally makes contact with touchscreen 112 using any suitable object or appendage, such as a stylus, afinger, and so forth. In some embodiments, the user interface isdesigned to work primarily with finger-based contacts and gestures,which can be less precise than stylus-based input due to the larger areaof contact of a finger on the touch screen. In some embodiments, thedevice translates the rough finger-based input into a precisepointer/cursor position or command for performing the actions desired bythe user.

In some embodiments, in addition to the touch screen, device 100optionally includes a touchpad (not shown) for activating ordeactivating particular functions. In some embodiments, the touchpad isa touch-sensitive area of the device that, unlike the touch screen, doesnot display visual output. The touchpad is, optionally, atouch-sensitive surface that is separate from touch screen 112 or anextension of the touch-sensitive surface formed by the touch screen.

Optical sensor 164 receives light from theenvironment, projected through one or more lenses, and converts thelight to data representing an image. In conjunction with imaging module143 (also called a camera module), optical sensor 164 optionallycaptures still images or video. In some embodiments, an optical sensoris located on the back of device 100, opposite touch screen display 112on the front of the device so that the touch screen display is enabledfor use as a viewfinder for still and/or video image acquisition. Insome embodiments, an optical sensor is located on the front of thedevice so that the user's image is, optionally, obtained for videoconferencing while the user views the other video conferenceparticipants on the touch screen display. In some embodiments, theposition of optical sensor 164 can be changed by the user (e.g., byrotating the lens and the sensor in the device housing) so that a singleoptical sensor 164 is used along with the touch screen display for bothvideo conferencing and still and/or video image acquisition.

Contact/motion module 130 optionally detects contact with touch screen112 (in conjunction with display controller 156) and othertouch-sensitive devices (e.g., a touchpad or physical click wheel).Contact/motion module 130 includes various software components forperforming various operations related to detection of contact, such asdetermining if contact has occurred (e.g., detecting a finger-downevent), determining an intensity of the contact (e.g., the force orpressure of the contact or a substitute for the force or pressure of thecontact), determining if there is movement of the contact and trackingthe movement across the touch-sensitive surface (e.g., detecting one ormore finger-dragging events), and determining if the contact has ceased(e.g., detecting a finger-up event or a break in contact).Contact/motion module 130 receives contact data from the touch-sensitivesurface. Determining movement of the point of contact, which isrepresented by a series of contact data, optionally includes determiningspeed (magnitude), velocity (magnitude and direction), and/or anacceleration (a change in magnitude and/or direction) of the point ofcontact. These operations are, optionally, applied to single contacts(e.g., one finger contacts) or to multiple simultaneous contacts (e.g.,“multitouch”/multiple finger contacts). In some embodiments,contact/motion module 130 and display controller 156 detect contact on atouchpad.

In some embodiments, contact/motion module 130 uses a set of one or moreintensity thresholds to determine whether an operation has beenperformed by a user (e.g., to determine whether a user has “clicked” onan icon). In some embodiments, at least a subset of the intensitythresholds are determined in accordance with software parameters (e.g.,the intensity thresholds are not determined by the activation thresholdsof particular physical actuators and can be adjusted without changingthe physical hardware of device 100). For example, a mouse “click”threshold of a trackpad or touch screen display can be set to any of alarge range of predefined threshold values without changing the trackpador touch screen display hardware. Additionally, in some implementations,a user of the device is provided with software settings for adjustingone or more of the set of intensity thresholds (e.g., by adjustingindividual intensity thresholds and/or by adjusting a plurality ofintensity thresholds at once with a system-level click “intensity”parameter).

Contact/motion module 130 optionally detects a gesture input by a user.Different gestures on the touch-sensitive surface have different contactpatterns (e.g., different motions, timings, and/or intensities ofdetected contacts). Thus, a gesture is, optionally, detected bydetecting a particular contact pattern. For example, detecting a fingertap gesture includes detecting a finger-down event followed by detectinga finger-up (liftoff) event at the same position (or substantially thesame position) as the finger-down event (e.g., at the position of anicon). As another example, detecting a finger swipe gesture on thetouch-sensitive surface includes detecting a finger-down event followedby detecting one or more finger-dragging events, and subsequentlyfollowed by detecting a finger-up (liftoff) event.

Each of the above-identified modules and applications corresponds to aset of executable instructions for performing one or more functionsdescribed above and the methods described in this application (e.g., thecomputer-implemented methods and other information processing methodsdescribed herein). These modules (e.g., sets of instructions) need notbe implemented as separate software programs, procedures, or modules,and thus various subsets of these modules are, optionally, combined orotherwise rearranged in various embodiments. For example, video playermodule is, optionally, combined with music player module into a singlemodule (e.g., video and music player module 152, FIG. 1A). In someembodiments, memory 102 optionally stores a subset of the modules anddata structures identified above. Furthermore, memory 102 optionallystores additional modules and data structures not described above.

In some embodiments, device 100 is a device where operation of apredefined set of functions on the device is performed exclusivelythrough a touch screen and/or a touchpad. By using a touch screen and/ora touchpad as the primary input control device for operation of device100, the number of physical input control devices (such as push buttons,dials, and the like) on device 100 is, optionally, reduced.

The predefined set of functions that are performed exclusively through atouch screen and/or a touchpad optionally include navigation betweenuser interfaces. In some embodiments, the touchpad, when touched by theuser, navigates device 100 to a main, home, or root menu from any userinterface that is displayed on device 100. In such embodiments, a “menubutton” is implemented using a touchpad. In some other embodiments, themenu button is a physical push button or other physical input controldevice instead of a touchpad.

FIG. 1B is a block diagram illustrating exemplary components for eventhandling in accordance with some embodiments. In some embodiments,memory 102 (FIG. 1A) or 370 (FIG. 3 ) includes event sorter 170 (e.g.,in operating system 126) and a respective application 136-1 (e.g., anyof the aforementioned applications 137-151, 155, 380-390).

Event sorter 170 receives event information and determines theapplication 136-1 and application view 191 of application 136-1 to whichto deliver the event information. Event sorter 170 includes eventmonitor 171 and event dispatcher module 174. In some embodiments,application 136-1 includes application internal state 192, whichindicates the current application view(s) displayed on touch-sensitivedisplay 112 when the application is active or executing. In someembodiments, device/global internal state 157 is used by event sorter170 to determine which application(s) is (are) currently active, andapplication internal state 192 is used by event sorter 170 to determineapplication views 191 to which to deliver event information.

In some embodiments, application internal state 192 includes additionalinformation, such as one or more of: resume information to be used whenapplication 136-1 resumes execution, user interface state informationthat indicates information being displayed or that is ready for displayby application 136-1, a state queue for enabling the user to go back toa prior state or view of application 136-1, and a redo/undo queue ofprevious actions taken by the user.

Event monitor 171 receives event information from peripherals interface118. Event information includes information about a sub-event (e.g., auser touch on touch-sensitive display 112, as part of a multi-touchgesture). Peripherals interface 118 transmits information it receivesfrom I/O subsystem 106 or a sensor, such as proximity sensor 166,accelerometer(s) 168, and/or microphone 113 (through audio circuitry110). Information that peripherals interface 118 receives from I/Osubsystem 106 includes information from touch-sensitive display 112 or atouch-sensitive surface.

In some embodiments, event monitor 171 sends requests to the peripheralsinterface 118 at predetermined intervals. In response, peripheralsinterface 118 transmits event information. In other embodiments,peripherals interface 118 transmits event information only when there isa significant event (e.g., receiving an input above a predeterminednoise threshold and/or for more than a predetermined duration).

In some embodiments, event sorter 170 also includes a hit viewdetermination module 172 and/or an active event recognizer determinationmodule 173.

Hit view determination module 172 provides software procedures fordetermining where a sub-event has taken place within one or more viewswhen touch-sensitive display 112 displays more than one view. Views aremade up of controls and other elements that a user can see on thedisplay.

Another aspect of the user interface associated with an application is aset of views, sometimes herein called application views or userinterface windows, in which information is displayed and touch-basedgestures occur. The application views (of a respective application) inwhich a touch is detected optionally correspond to programmatic levelswithin a programmatic or view hierarchy of the application. For example,the lowest level view in which a touch is detected is, optionally,called the hit view, and the set of events that are recognized as properinputs are, optionally, determined based, at least in part, on the hitview of the initial touch that begins a touch-based gesture.

Hit view determination module 172 receives information related tosub-events of a touch-based gesture. When an application has multipleviews organized in a hierarchy, hit view determination module 172identifies a hit view as the lowest view in the hierarchy which shouldhandle the sub-event. In most circumstances, the hit view is the lowestlevel view in which an initiating sub-event occurs (e.g., the firstsub-event in the sequence of sub-events that form an event or potentialevent). Once the hit view is identified by the hit view determinationmodule 172, the hit view typically receives all sub-events related tothe same touch or input source for which it was identified as the hitview.

Active event recognizer determination module 173 determines which viewor views within a view hierarchy should receive a particular sequence ofsub-events. In some embodiments, active event recognizer determinationmodule 173 determines that only the hit view should receive a particularsequence of sub-events. In other embodiments, active event recognizerdetermination module 173 determines that all views that include thephysical location of a sub-event are actively involved views, andtherefore determines that all actively involved views should receive aparticular sequence of sub-events. In other embodiments, even if touchsub-events were entirely confined to the area associated with oneparticular view, views higher in the hierarchy would still remain asactively involved views.

Event dispatcher module 174 dispatches the event information to an eventrecognizer (e.g., event recognizer 180). In embodiments including activeevent recognizer determination module 173, event dispatcher module 174delivers the event information to an event recognizer determined byactive event recognizer determination module 173. In some embodiments,event dispatcher module 174 stores in an event queue the eventinformation, which is retrieved by a respective event receiver 182.

In some embodiments, operating system 126 includes event sorter 170.Alternatively, application 136-1 includes event sorter 170. In yet otherembodiments, event sorter 170 is a stand-alone module, or a part ofanother module stored in memory 102, such as contact/motion module 130.

In some embodiments, application 136-1 includes a plurality of eventhandlers 190 and one or more application views 191, each of whichincludes instructions for handling touch events that occur within arespective view of the application's user interface. Each applicationview 191 of the application 136-1 includes one or more event recognizers180. Typically, a respective application view 191 includes a pluralityof event recognizers 180. In other embodiments, one or more of eventrecognizers 180 are part of a separate module, such as a user interfacekit (not shown) or a higher level object from which application 136-1inherits methods and other properties. In some embodiments, a respectiveevent handler 190 includes one or more of: data updater 176, objectupdater 177, GUI updater 178, and/or event data 179 received from eventsorter 170. Event handler 190 optionally utilizes or calls data updater176, object updater 177, or GUI updater 178 to update the applicationinternal state 192. Alternatively, one or more of the application views191 include one or more respective event handlers 190. Also, in someembodiments, one or more of data updater 176, object updater 177, andGUI updater 178 are included in a respective application view 191.

A respective event recognizer 180 receives event information (e.g.,event data 179) from event sorter 170 and identifies an event from theevent information. Event recognizer 180 includes event receiver 182 andevent comparator 184. In some embodiments, event recognizer 180 alsoincludes at least a subset of: metadata 183, and event deliveryinstructions 188 (which optionally include sub-event deliveryinstructions).

Event receiver 182 receives event information from event sorter 170. Theevent information includes information about a sub-event, for example, atouch or a touch movement. Depending on the sub-event, the eventinformation also includes additional information, such as location ofthe sub-event. When the sub-event concerns motion of a touch, the eventinformation optionally also includes speed and direction of thesub-event. In some embodiments, events include rotation of the devicefrom one orientation to another (e.g., from a portrait orientation to alandscape orientation, or vice versa), and the event informationincludes corresponding information about the current orientation (alsocalled device attitude) of the device.

Event comparator 184 compares the event information to predefined eventor sub-event definitions and, based on the comparison, determines anevent or sub-event, or determines or updates the state of an event orsub-event. In some embodiments, event comparator 184 includes eventdefinitions 186. Event definitions 186 contain definitions of events(e.g., predefined sequences of sub-events), for example, event 1(187-1), event 2 (187-2), and others. In some embodiments, sub-events inan event (187) include, for example, touch begin, touch end, touchmovement, touch cancellation, and multiple touching. In one example, thedefinition for event 1 (187-1) is a double tap on a displayed object.The double tap, for example, comprises a first touch (touch begin) onthe displayed object for a predetermined phase, a first liftoff (touchend) for a predetermined phase, a second touch (touch begin) on thedisplayed object for a predetermined phase, and a second liftoff (touchend) for a predetermined phase. In another example, the definition forevent 2 (187-2) is a dragging on a displayed object. The dragging, forexample, comprises a touch (or contact) on the displayed object for apredetermined phase, a movement of the touch across touch-sensitivedisplay 112, and liftoff of the touch (touch end). In some embodiments,the event also includes information for one or more associated eventhandlers 190.

In some embodiments, event definition 187 includes a definition of anevent for a respective user-interface object. In some embodiments, eventcomparator 184 performs a hit test to determine which user-interfaceobject is associated with a sub-event. For example, in an applicationview in which three user-interface objects are displayed ontouch-sensitive display 112, when a touch is detected on touch-sensitivedisplay 112, event comparator 184 performs a hit test to determine whichof the three user-interface objects is associated with the touch(sub-event). If each displayed object is associated with a respectiveevent handler 190, the event comparator uses the result of the hit testto determine which event handler 190 should be activated. For example,event comparator 184 selects an event handler associated with thesub-event and the object triggering the hit test.

In some embodiments, the definition for a respective event (187) alsoincludes delayed actions that delay delivery of the event informationuntil after it has been determined whether the sequence of sub-eventsdoes or does not correspond to the event recognizer's event type.

When a respective event recognizer 180 determines that the series ofsub-events do not match any of the events in event definitions 186, therespective event recognizer 180 enters an event impossible, eventfailed, or event ended state, after which it disregards subsequentsub-events of the touch-based gesture. In this situation, other eventrecognizers, if any, that remain active for the hit view continue totrack and process sub-events of an ongoing touch-based gesture.

In some embodiments, a respective event recognizer 180 includes metadata183 with configurable properties, flags, and/or lists that indicate howthe event delivery system should perform sub-event delivery to activelyinvolved event recognizers. In some embodiments, metadata 183 includesconfigurable properties, flags, and/or lists that indicate how eventrecognizers interact, or are enabled to interact, with one another. Insome embodiments, metadata 183 includes configurable properties, flags,and/or lists that indicate whether sub-events are delivered to varyinglevels in the view or programmatic hierarchy.

In some embodiments, a respective event recognizer 180 activates eventhandler 190 associated with an event when one or more particularsub-events of an event are recognized. In some embodiments, a respectiveevent recognizer 180 delivers event information associated with theevent to event handler 190. Activating an event handler 190 is distinctfrom sending (and deferred sending) sub-events to a respective hit view.In some embodiments, event recognizer 180 throws a flag associated withthe recognized event, and event handler 190 associated with the flagcatches the flag and performs a predefined process.

In some embodiments, event delivery instructions 188 include sub-eventdelivery instructions that deliver event information about a sub-eventwithout activating an event handler. Instead, the sub-event deliveryinstructions deliver event information to event handlers associated withthe series of sub-events or to actively involved views. Event handlersassociated with the series of sub-events or with actively involved viewsreceive the event information and perform a predetermined process.

In some embodiments, data updater 176 creates and updates data used inapplication 136-1. For example, data updater 176 updates the telephonenumber used in contacts module 137, or stores a video file used in videoplayer module. In some embodiments, object updater 177 creates andupdates objects used in application 136-1. For example, object updater177 creates a new user-interface object or updates the position of auser-interface object. GUI updater 178 updates the GUI. For example, GUIupdater 178 prepares display information and sends it to graphics module132 for display on a touch-sensitive display.

In some embodiments, event handler(s) 190 includes or has access to dataupdater 176, object updater 177, and GUI updater 178. In someembodiments, data updater 176, object updater 177, and GUI updater 178are included in a single module of a respective application 136-1 orapplication view 191. In other embodiments, they are included in two ormore software modules.

It shall be understood that the foregoing discussion regarding eventhandling of user touches on touch-sensitive displays also applies toother forms of user inputs to operate multifunction devices 100 withinput devices, not all of which are initiated on touch screens. Forexample, mouse movement and mouse button presses, optionally coordinatedwith single or multiple keyboard presses or holds; contact movementssuch as taps, drags, scrolls, etc. on touchpads; pen stylus inputs;movement of the device; oral instructions; detected eye movements;biometric inputs; and/or any combination thereof are optionally utilizedas inputs corresponding to sub-events which define an event to berecognized.

Push button 206 is, optionally, used to turn the power on/offon the device by depressing the button and holding the button in thedepressed state for a predefined time interval; to lock the device bydepressing the button and releasing the button before the predefinedtime interval has elapsed; and/or to unlock the device or initiate anunlock process. In an alternative embodiment, device 100 also acceptsverbal input for activation or deactivation of some functions throughmicrophone 113. Device 100 also, optionally, includes one or morecontact intensity sensors 165 for detecting intensity of contacts ontouch screen 112 and/or one or more tactile output generators 167 forgenerating tactile outputs for a user of device 100.

FIG. 3 is a block diagram of an exemplary multifunction device with adisplay and a touch-sensitive surface in accordance with someembodiments. Device 300 need not be portable. In some embodiments,device 300 is a laptop computer, a desktop computer, a tablet computer,a multimedia player device, a navigation device, an educational device(such as a child's learning toy), a gaming system, or a control device(e.g., a home or industrial controller). Device 300 typically includesone or more processing units (CPUs) 310, one or more network or othercommunications interfaces 360, memory 370, and one or more communicationbuses 320 for interconnecting these components. Communication buses 320optionally include circuitry (sometimes called a chipset) thatinterconnects and controls communications between system components.Device 300 includes input/output (I/O) interface 330 comprising display340, which is typically a touch screen display.

Memory 370 optionally includes one or more storage devicesremotely located from CPU(s) 310. In some embodiments, memory 370 storesprograms, modules, and data structures analogous to the programs,modules, and data structures stored in memory 102 of portablemultifunction device 100 (FIG. 1A), or a subset thereof. Furthermore,memory 370 optionally stores additional programs, modules, and datastructures not present in memory 102 of portable multifunction device100. For example, memory 370 of device 300 optionally stores drawingmodule 380, presentation module 382, word processing module 384, websitecreation module 386, disk authoring module 388, and/or spreadsheetmodule 390, while memory 102 of portable multifunction device 100 (FIG.1A) optionally does not store these modules.

Each of the above-identified elements in FIG. 3 is, optionally, storedin one or more of the previously mentioned memory devices. Each of theabove-identified modules corresponds to a set of instructions forperforming a function described above. The above-identified modules orprograms (e.g., sets of instructions) need not be implemented asseparate software programs, procedures, or modules, and thus varioussubsets of these modules are, optionally, combined or otherwiserearranged in various embodiments. In some embodiments, memory 370optionally stores a subset of the modules and data structures identifiedabove. Furthermore, memory 370 optionally stores additional modules anddata structures not described above.

Attention is now directed towards embodiments of user interfaces thatare, optionally, implemented on, for example, portable multifunctiondevice 100.

FIG. 4A illustrates an exemplary user interface for a menu ofapplications on portable multifunction device 100 in accordance withsome embodiments. Similar user interfaces are, optionally, implementedon device 300. In some embodiments, user interface 400 includes thefollowing elements, or a subset or superset thereof:

-   -   Signal strength indicator(s) 402 for wireless communication(s),        such as cellular and Wi-Fi signals;    -   Time 404;    -   Bluetooth indicator 405;    -   Battery status indicator 406;    -   Tray 408 with icons for frequently used applications, such as:        -   Icon 416 for telephone module 138, labeled “Phone,” which            optionally includes an indicator 414 of the number of missed            calls or voicemail messages;        -   Icon 418 for e-mail client module 140, labeled “Mail,” which            optionally includes an indicator 410 of the number of unread            e-mails;        -   Icon 420 for browser module 147, labeled “Browser;” and        -   Icon 422 for video and music player module 152, also            referred to as iPod (trademark of Apple Inc.) module 152,            labeled “iPod;” and    -   Icons for other applications, such as:        -   Icon 424 for IM module 141, labeled “Messages;”        -   Icon 426 for calendar module 148, labeled “Calendar;”        -   Icon 428 for image management module 144, labeled “Photos;”        -   Icon 430 for camera module 143, labeled “Camera;”        -   Icon 432 for online video module 155, labeled “Online            Video;”        -   Icon 434 for stocks widget 149-2, labeled “Stocks;”        -   Icon 436 for map module 154, labeled “Maps;”        -   Icon 438 for weather widget 149-1, labeled “Weather;”        -   Icon 440 for alarm clock widget 149-4, labeled “Clock;”        -   Icon 442 for workout support module 142, labeled “Workout            Support;”        -   Icon 444 for notes module 153, labeled “Notes;” and        -   Icon 446 for a settings application or module, labeled            “Settings,” which provides access to settings for device 100            and its various applications 136.

It should be noted that the icon labels illustrated in FIG. 4A aremerely exemplary. For example, icon 422 for video and music playermodule 152 is labeled “Music” or “Music Player.” Other labels are,optionally, used for various application icons. In some embodiments, alabel for a respective application icon includes a name of anapplication corresponding to the respective application icon. In someembodiments, a label for a particular application icon is distinct froma name of an application corresponding to the particular applicationicon.

FIG. 4B illustrates an exemplary user interface on a device (e.g.,device 300, FIG. 3 ) with a touch-sensitive surface 451 (e.g., a tabletor touchpad 355, FIG. 3 ) that is separate from the display 450 (e.g.,touch screen display 112). Device 300 also, optionally, includes one ormore contact intensity sensors (e.g., one or more of sensors 359) fordetecting intensity of contacts on touch-sensitive surface 451 and/orone or more tactile output generators 357 for generating tactile outputsfor a user of device 300.

Although some of the examples that follow will be given with referenceto inputs on touch screen display 112 (where the touch-sensitive surfaceand the display are combined), in some embodiments, the device detectsinputs on a touch-sensitive surface that is separate from the display,as shown in FIG. 4B. In some embodiments, the touch-sensitive surface(e.g., 451 in FIG. 4B) has a primary axis (e.g., 452 in FIG. 4B) thatcorresponds to a primary axis (e.g., 453 in FIG. 4B) on the display(e.g., 450). In accordance with these embodiments, the device detectscontacts (e.g., 460 and 462 in FIG. 4B) with the touch-sensitive surface451 at locations that correspond to respective locations on the display(e.g., in FIG. 4B, 460 corresponds to 468 and 462 corresponds to 470).In this way, user inputs (e.g., contacts 460 and 462, and movementsthereof) detected by the device on the touch-sensitive surface (e.g.,451 in FIG. 4B) are used by the device to manipulate the user interfaceon the display (e.g., 450 in FIG. 4B) of the multifunction device whenthe touch-sensitive surface is separate from the display. It should beunderstood that similar methods are, optionally, used for other userinterfaces described herein.

Additionally, while the following examples are given primarily withreference to finger inputs (e.g., finger contacts, finger tap gestures,finger swipe gestures), it should be understood that, in someembodiments, one or more of the finger inputs are replaced with inputfrom another input device (e.g., a mouse-based input or stylus input).For example, a swipe gesture is, optionally, replaced with a mouse click(e.g., instead of a contact) followed by movement of the cursor alongthe path of the swipe (e.g., instead of movement of the contact). Asanother example, a tap gesture is, optionally, replaced with a mouseclick while the cursor is located over the location of the tap gesture(e.g., instead of detection of the contact followed by ceasing to detectthe contact). Similarly, when multiple user inputs are simultaneouslydetected, it should be understood that multiple computer mice are,optionally, used simultaneously, or a mouse and finger contacts are,optionally, used simultaneously.

FIG. 5A illustrates exemplary personal electronic device 500. Device 500includes body 502. In some embodiments, device 500 can include some orall of the features described with respect to devices 100 and 300 (e.g.,FIGS. 1A-4B). In some embodiments, device 500 has touch-sensitivedisplay screen 504, hereafter touch screen 504. Alternatively, or inaddition to touch screen 504, device 500 has a display and atouch-sensitive surface. As with devices 100 and 300, in someembodiments, touch screen 504 (or the touch-sensitive surface)optionally includes one or more intensity sensors for detectingintensity of contacts (e.g., touches) being applied. The one or moreintensity sensors of touch screen 504 (or the touch-sensitive surface)can provide output data that represents the intensity of touches. Theuser interface of device 500 can respond to touches based on theirintensity, meaning that touches of different intensities can invokedifferent user interface operations on device 500.

Exemplary techniques for detecting and processing touch intensity arefound, for example, in related applications: International PatentApplication Serial No. PCT/US2013/040061, titled “Device, Method, andGraphical User Interface for Displaying User Interface ObjectsCorresponding to an Application,” filed May 8, 2013, published as WIPOPublication No. WO/2013/169849, and International Patent ApplicationSerial No. PCT/US2013/069483, titled “Device, Method, and Graphical UserInterface for Transitioning Between Touch Input to Display OutputRelationships,” filed Nov. 11, 2013, published as WIPO Publication No.WO/2014/105276, each of which is hereby incorporated by reference intheir entirety.

In some embodiments, device 500 has one or more input mechanisms 506 and508. Input mechanisms 506 and 508, if included, can be physical.Examples of physical input mechanisms include push buttons and rotatablemechanisms. In some embodiments, device 500 has one or more attachmentmechanisms. Such attachment mechanisms, if included, can permitattachment of device 500 with, for example, hats, eyewear, earrings,necklaces, shirts, jackets, bracelets, watch straps, chains, trousers,belts, shoes, purses, backpacks, and so forth. These attachmentmechanisms permit device 500 to be worn by a user.

FIG. 5B depicts exemplary personal electronic device 500. In someembodiments, device 500 can include some or all of the componentsdescribed with respect to FIGS. 1A, 1B, and 3. Device 500 has bus 512that operatively couples I/O section 514 with one or more computerprocessors 516 and memory 518. I/O section 514 can be connected todisplay 504, which can have touch-sensitive component 522 and,optionally, intensity sensor 524 (e.g., contact intensity sensor). Inaddition, I/O section 514 can be connected with communication unit 530for receiving application and operating system data, using Wi-Fi,Bluetooth, near field communication (NFC), cellular, and/or otherwireless communication techniques. Device 500 can include inputmechanisms 506 and/or 508. Input mechanism 506 is, optionally, arotatable input device or a depressible and rotatable input device, forexample. Input mechanism 508 is, optionally, a button, in some examples.

Input mechanism 508 is, optionally, a microphone, in some examples.Personal electronic device 500 optionally includes various sensors, suchas GPS sensor 532, accelerometer 534, directional sensor 540 (e.g.,compass), gyroscope 536, motion sensor 538, and/or a combinationthereof, all of which can be operatively connected to I/O section 514.

Memory 518 of personal electronic device 500 can include one or morenon-transitory computer-readable storage mediums, for storingcomputer-executable instructions, which, when executed by one or morecomputer processors 516, for example, can cause the computer processorsto perform the techniques described below, including processes 700(FIGS. 7A-7C), 900 (FIGS. 9A-9C), 1200 (FIGS. 12A-12B), 1400 (FIGS.14A-14B), and 1500 (FIG. 15 ). A computer-readable storage medium can beany medium that can tangibly contain or store computer-executableinstructions for use by or in connection with the instruction executionsystem, apparatus, or device. In some examples, the storage medium is atransitory computer-readable storage medium. In some examples, thestorage medium is a non-transitory computer-readable storage medium. Thenon-transitory computer-readable storage medium can include, but is notlimited to, magnetic, optical, and/or semiconductor storages. Examplesof such storage include magnetic disks, optical discs based on CD, DVD,or Blu-ray technologies, as well as persistent solid-state memory suchas flash, solid-state drives, and the like. Personal electronic device500 is not limited to the components and configuration of FIG. 5B, butcan include other or additional components in multiple configurations.

As used here, the term “affordance” refers to a user-interactivegraphical user interface object that is, optionally, displayed on thedisplay screen of devices 100, 300, and/or 500 (FIGS. 1A, 3, and 5A-5B).For example, an image (e.g., icon), a button, and text (e.g., hyperlink)each optionally constitute an affordance.

As used herein, the term “focus selector” refers to an input elementthat indicates a current part of a user interface with which a user isinteracting. In some implementations that include a cursor or otherlocation marker, the cursor acts as a “focus selector” so that when aninput (e.g., a press input) is detected on a touch-sensitive surface(e.g., touchpad 355 in FIG. 3 or touch-sensitive surface 451 in FIG. 4B)while the cursor is over a particular user interface element (e.g., abutton, window, slider, or other user interface element), the particularuser interface element is adjusted in accordance with the detectedinput. In some implementations that include a touch screen display(e.g., touch-sensitive display system 112 in FIG. 1A or touch screen 112in FIG. 4A) that enables direct interaction with user interface elementson the touch screen display, a detected contact on the touch screen actsas a “focus selector” so that when an input (e.g., a press input by thecontact) is detected on the touch screen display at a location of aparticular user interface element (e.g., a button, window, slider, orother user interface element), the particular user interface element isadjusted in accordance with the detected input. In some implementations,focus is moved from one region of a user interface to another region ofthe user interface without corresponding movement of a cursor ormovement of a contact on a touch screen display (e.g., by using a tabkey or arrow keys to move focus from one button to another button); inthese implementations, the focus selector moves in accordance withmovement of focus between different regions of the user interface.Without regard to the specific form taken by the focus selector, thefocus selector is generally the user interface element (or contact on atouch screen display) that is controlled by the user so as tocommunicate the user's intended interaction with the user interface(e.g., by indicating, to the device, the element of the user interfacewith which the user is intending to interact). For example, the locationof a focus selector (e.g., a cursor, a contact, or a selection box) overa respective button while a press input is detected on thetouch-sensitive surface (e.g., a touchpad or touch screen) will indicatethat the user is intending to activate the respective button (as opposedto other user interface elements shown on a display of the device).

As used in the specification and claims, the term “characteristicintensity” of a contact refers to a characteristic of the contact basedon one or more intensities of the contact. In some embodiments, thecharacteristic intensity is based on multiple intensity samples. Thecharacteristic intensity is, optionally, based on a predefined number ofintensity samples, or a set of intensity samples collected during apredetermined time period (e.g., 0.05, 0.1, 0.2, 0.5, 1, 2, 5, 10seconds) relative to a predefined event (e.g., after detecting thecontact, prior to detecting liftoff of the contact, before or afterdetecting a start of movement of the contact, prior to detecting an endof the contact, before or after detecting an increase in intensity ofthe contact, and/or before or after detecting a decrease in intensity ofthe contact). A characteristic intensity of a contact is, optionally,based on one or more of: a maximum value of the intensities of thecontact, a mean value of the intensities of the contact, an averagevalue of the intensities of the contact, a top 10 percentile value ofthe intensities of the contact, a value at the half maximum of theintensities of the contact, a value at the 90 percent maximum of theintensities of the contact, or the like. In some embodiments, theduration of the contact is used in determining the characteristicintensity (e.g., when the characteristic intensity is an average of theintensity of the contact over time). In some embodiments, thecharacteristic intensity is compared to a set of one or more intensitythresholds to determine whether an operation has been performed by auser. For example, the set of one or more intensity thresholdsoptionally includes a first intensity threshold and a second intensitythreshold. In this example, a contact with a characteristic intensitythat does not exceed the first threshold results in a first operation, acontact with a characteristic intensity that exceeds the first intensitythreshold and does not exceed the second intensity threshold results ina second operation, and a contact with a characteristic intensity thatexceeds the second threshold results in a third operation. In someembodiments, a comparison between the characteristic intensity and oneor more thresholds is used to determine whether or not to perform one ormore operations (e.g., whether to perform a respective operation orforgo performing the respective operation), rather than being used todetermine whether to perform a first operation or a second operation.

FIG. 5C illustrates detecting a plurality of contacts 552A-552E ontouch-sensitive display screen 504 with a plurality of intensity sensors524A-524D. FIG. 5C additionally includes intensity diagrams that showthe current intensity measurements of the intensity sensors 524A-524Drelative to units of intensity. In this example, the intensitymeasurements of intensity sensors 524A and 524D are each 9 units ofintensity, and the intensity measurements of intensity sensors 524B and524C are each 7 units of intensity. In some implementations, anaggregate intensity is the sum of the intensity measurements of theplurality of intensity sensors 524A-524D, which in this example is 32intensity units. In some embodiments, each contact is assigned arespective intensity that is a portion of the aggregate intensity. FIG.5D illustrates assigning the aggregate intensity to contacts 552A-552Ebased on their distance from the center of force 554. In this example,each of contacts 552A, 552B, and 552E are assigned an intensity ofcontact of 8 intensity units of the aggregate intensity, and each ofcontacts 552C and 552D are assigned an intensity of contact of 4intensity units of the aggregate intensity. More generally, in someimplementations, each contact j is assigned a respective intensity Ijthat is a portion of the aggregate intensity, A, in accordance with apredefined mathematical function, Ij=A·(Dj/ΣDi), where Dj is thedistance of the respective contact j to the center of force, and ΣDi isthe sum of the distances of all the respective contacts (e.g., i=1 tolast) to the center of force. The operations described with reference toFIGS. 5C-5D can be performed using an electronic device similar oridentical to device 100, 300, or 500. In some embodiments, acharacteristic intensity of a contact is based on one or moreintensities of the contact. In some embodiments, the intensity sensorsare used to determine a single characteristic intensity (e.g., a singlecharacteristic intensity of a single contact). It should be noted thatthe intensity diagrams are not part of a displayed user interface, butare included in FIGS. 5C-5D to aid the reader.

In some embodiments, a portion of a gesture is identified for purposesof determining a characteristic intensity. For example, atouch-sensitive surface optionally receives a continuous swipe contacttransitioning from a start location and reaching an end location, atwhich point the intensity of the contact increases. In this example, thecharacteristic intensity of the contact at the end location is,optionally, based on only a portion of the continuous swipe contact, andnot the entire swipe contact (e.g., only the portion of the swipecontact at the end location). In some embodiments, a smoothing algorithmis, optionally, applied to the intensities of the swipe contact prior todetermining the characteristic intensity of the contact. For example,the smoothing algorithm optionally includes one or more of: anunweighted sliding-average smoothing algorithm, a triangular smoothingalgorithm, a median filter smoothing algorithm, and/or an exponentialsmoothing algorithm. In some circumstances, these smoothing algorithmseliminate narrow spikes or dips in the intensities of the swipe contactfor purposes of determining a characteristic intensity.

The intensity of a contact on the touch-sensitive surface is,optionally, characterized relative to one or more intensity thresholds,such as a contact-detection intensity threshold, a light press intensitythreshold, a deep press intensity threshold, and/or one or more otherintensity thresholds. In some embodiments, the light press intensitythreshold corresponds to an intensity at which the device will performoperations typically associated with clicking a button of a physicalmouse or a trackpad. In some embodiments, the deep press intensitythreshold corresponds to an intensity at which the device will performoperations that are different from operations typically associated withclicking a button of a physical mouse or a trackpad. In someembodiments, when a contact is detected with a characteristic intensitybelow the light press intensity threshold (e.g., and above a nominalcontact-detection intensity threshold below which the contact is nolonger detected), the device will move a focus selector in accordancewith movement of the contact on the touch-sensitive surface withoutperforming an operation associated with the light press intensitythreshold or the deep press intensity threshold. Generally, unlessotherwise stated, these intensity thresholds are consistent betweendifferent sets of user interface figures.

An increase of characteristic intensity of the contact from an intensitybelow the light press intensity threshold to an intensity between thelight press intensity threshold and the deep press intensity thresholdis sometimes referred to as a “light press” input. An increase ofcharacteristic intensity of the contact from an intensity below the deeppress intensity threshold to an intensity above the deep press intensitythreshold is sometimes referred to as a “deep press” input. An increaseof characteristic intensity of the contact from an intensity below thecontact-detection intensity threshold to an intensity between thecontact-detection intensity threshold and the light press intensitythreshold is sometimes referred to as detecting the contact on thetouch-surface. A decrease of characteristic intensity of the contactfrom an intensity above the contact-detection intensity threshold to anintensity below the contact-detection intensity threshold is sometimesreferred to as detecting liftoff of the contact from the touch-surface.In some embodiments, the contact-detection intensity threshold is zero.In some embodiments, the contact-detection intensity threshold isgreater than zero.

In some embodiments described herein, one or more operations areperformed in response to detecting a gesture that includes a respectivepress input or in response to detecting the respective press inputperformed with a respective contact (or a plurality of contacts), wherethe respective press input is detected based at least in part ondetecting an increase in intensity of the contact (or plurality ofcontacts) above a press-input intensity threshold. In some embodiments,the respective operation is performed in response to detecting theincrease in intensity of the respective contact above the press-inputintensity threshold (e.g., a “down stroke” of the respective pressinput). In some embodiments, the press input includes an increase inintensity of the respective contact above the press-input intensitythreshold and a subsequent decrease in intensity of the contact belowthe press-input intensity threshold, and the respective operation isperformed in response to detecting the subsequent decrease in intensityof the respective contact below the press-input threshold (e.g., an “upstroke” of the respective press input).

FIGS. 5E-5H illustrate detection of a gesture that includes a pressinput that corresponds to an increase in intensity of a contact 562 froman intensity below a light press intensity threshold (e.g., “IT_(L)”) inFIG. 5E, to an intensity above a deep press intensity threshold (e.g.,“IT_(D)”) in FIG. 5H. The gesture performed with contact 562 is detectedon touch-sensitive surface 560 while cursor 576 is displayed overapplication icon 572B corresponding to App 2, on a displayed userinterface 570 that includes application icons 572A-572D displayed inpredefined region 574. In some embodiments, the gesture is detected ontouch-sensitive display 504. The intensity sensors detect the intensityof contacts on touch-sensitive surface 560. The device determines thatthe intensity of contact 562 peaked above the deep press intensitythreshold (e.g., “IT_(D)”). Contact 562 is maintained on touch-sensitivesurface 560. In response to the detection of the gesture, and inaccordance with contact 562 having an intensity that goes above the deeppress intensity threshold (e.g., “IT_(D)”) during the gesture,reduced-scale representations 578A-578C (e.g., thumbnails) of recentlyopened documents for App 2 are displayed, as shown in FIGS. 5F-5H. Insome embodiments, the intensity, which is compared to the one or moreintensity thresholds, is the characteristic intensity of a contact. Itshould be noted that the intensity diagram for contact 562 is not partof a displayed user interface, but is included in FIGS. 5E-5H to aid thereader.

In some embodiments, the display of representations 578A-578C includesan animation. For example, representation 578A is initially displayed inproximity of application icon 572B, as shown in FIG. 5F. As theanimation proceeds, representation 578A moves upward and representation578B is displayed in proximity of application icon 572B, as shown inFIG. 5G. Then, representations 578A moves upward, 578B moves upwardtoward representation 578A, and representation 578C is displayed inproximity of application icon 572B, as shown in FIG. 5H. Representations578A-578C form an array above icon 572B. In some embodiments, theanimation progresses in accordance with an intensity of contact 562, asshown in FIGS. 5F-5G, where the representations 578A-578C appear andmove upwards as the intensity of contact 562 increases toward the deeppress intensity threshold (e.g., “IT_(D)”). In some embodiments, theintensity, on which the progress of the animation is based, is thecharacteristic intensity of the contact. The operations described withreference to FIGS. 5E-5H can be performed using an electronic devicesimilar or identical to device 100, 300, or 500.

In some embodiments, the device employs intensity hysteresis to avoidaccidental inputs sometimes termed “jitter,” where the device defines orselects a hysteresis intensity threshold with a predefined relationshipto the press-input intensity threshold (e.g., the hysteresis intensitythreshold is X intensity units lower than the press-input intensitythreshold or the hysteresis intensity threshold is 75%, 90%, or somereasonable proportion of the press-input intensity threshold). Thus, insome embodiments, the press input includes an increase in intensity ofthe respective contact above the press-input intensity threshold and asubsequent decrease in intensity of the contact below the hysteresisintensity threshold that corresponds to the press-input intensitythreshold, and the respective operation is performed in response todetecting the subsequent decrease in intensity of the respective contactbelow the hysteresis intensity threshold (e.g., an “up stroke” of therespective press input). Similarly, in some embodiments, the press inputis detected only when the device detects an increase in intensity of thecontact from an intensity at or below the hysteresis intensity thresholdto an intensity at or above the press-input intensity threshold and,optionally, a subsequent decrease in intensity of the contact to anintensity at or below the hysteresis intensity, and the respectiveoperation is performed in response to detecting the press input (e.g.,the increase in intensity of the contact or the decrease in intensity ofthe contact, depending on the circumstances).

For ease of explanation, the descriptions of operations performed inresponse to a press input associated with a press-input intensitythreshold or in response to a gesture including the press input are,optionally, triggered in response to detecting either: an increase inintensity of a contact above the press-input intensity threshold, anincrease in intensity of a contact from an intensity below thehysteresis intensity threshold to an intensity above the press-inputintensity threshold, a decrease in intensity of the contact below thepress-input intensity threshold, and/or a decrease in intensity of thecontact below the hysteresis intensity threshold corresponding to thepress-input intensity threshold. Additionally, in examples where anoperation is described as being performed in response to detecting adecrease in intensity of a contact below the press-input intensitythreshold, the operation is, optionally, performed in response todetecting a decrease in intensity of the contact below a hysteresisintensity threshold corresponding to, and lower than, the press-inputintensity threshold.

As used herein, an “installed application” refers to a softwareapplication that has been downloaded onto an electronic device (e.g.,devices 100, 300, and/or 500) and is ready to be launched (e.g., becomeopened) on the device. In some embodiments, a downloaded applicationbecomes an installed application by way of an installation program thatextracts program portions from a downloaded package and integrates theextracted portions with the operating system of the computer system.

As used herein, the terms “open application” or “executing application”refer to a software application with retained state information (e.g.,as part of device/global internal state 157 and/or application internalstate 192). An open or executing application is, optionally, any one ofthe following types of applications:

-   -   an active application, which is currently displayed on a display        screen of the device that the application is being used on;    -   a background application (or background processes), which is not        currently displayed, but one or more processes for the        application are being processed by one or more processors; and    -   a suspended or hibernated application, which is not running, but        has state information that is stored in memory (volatile and        non-volatile, respectively) and that can be used to resume        execution of the application.

As used herein, the term “closed application” refers to softwareapplications without retained state information (e.g., state informationfor closed applications is not stored in a memory of the device).Accordingly, closing an application includes stopping and/or removingapplication processes for the application and removing state informationfor the application from the memory of the device. Generally, opening asecond application while in a first application does not close the firstapplication. When the second application is displayed and the firstapplication ceases to be displayed, the first application becomes abackground application.

Spatial management of audio includes techniques for modifyingcharacteristics of sound (e.g., by applying filters) such that alistener perceives the sound as being emitted from a particular locationin space (e.g., three-dimensional (3D) space). Such techniques can beachieved using speakers, such as headphones, earbuds, or loudspeakers.In some examples, such as when the listener is using headphones, abinaural simulation is used to recreate binaural cues that give thelistener the illusion that sound is coming from a particular location inspace. For example, the listener perceives the source of the sound ascoming from the left of the listener. For another example, the listenerperceives the source of the sound as passing by from left to right infront of the listener. This effect can be enhanced by using headtracking to adjust the binaural filters to create the illusion that thelocation of the source of the sound stays static in space, even when thelistener's head moves or rotates. In some examples, such as when thelisten is using loudspeakers, a similar effect is achieved by usingcrosstalk cancellation to give the listener the illusion that sound iscoming from a particular location in space.

Head-Related Transfer Functions (HRTFs) characterize how human earsreceive sound from various points in space. HRTFs may be based on one ormore of the direction, elevation, and distance the sound. By usingHRTFs, a device (e.g., device 100) applies different functions to audioto recreate the directivity patterns of human ears. In some examples, apair of HRTFs for two ears can be used to synthesize a binaural soundthat the listener perceives as coming from a particular point in spacein relation to the listener, such as above, below, in front of, behind,to the left, or to the right of the user, or a combination thereof. Apersonalized HRTF will provide better results for the listen for whomthe HRTF is personalized, as compared to a generic HRTF. In someexamples, HRTFs are applied for listeners that are using listeningdevices such as headphones, earphones, and earbuds.

For another example, when a device (e.g., device 100) produces soundusing two or more loudspeakers, sound from each loudspeaker is heardthrough the listener's respective closest ear, but also through thecontralateral ear, resulting in crosstalk. Effectively managingcancellation of this unintended crosstalk is helpful in modifying thesound such that a listener perceives the sound as being emitted from aparticular location in space.

A device (e.g., device 100, 300, 500) can also concurrently modify thecharacteristics of multiple audio sources (e.g., by applying differentfilters to respective sources) to give the listener the illusion thatthe sounds from the different audio sources are coming from respectivedifferent locations in space. Such techniques can be achieved usingheadphones or loudspeakers.

In some examples, modifying a stereo sound source such that a listenerperceives the sound as being emitted from a particular location in space(e.g., 3D space) includes creating a mono sound from the stereo sound.For example, the stereo sound includes a left audio channel and a rightaudio channel. The left audio channel includes a first instrument, forinstance, without including a second instrument. The second audiochannel includes the second instrument, for instance, without includingthe first instrument.

When placing the stereo sound source in space, the device optionallycombines the left audio channel and the right audio channel to form acombined channel audio, and then applies an interaural time differenceto the combined channel audio. Further, the device optionally (oralternatively) also applies an HRTF and/or cross cancellation to thecombined channel audio before generating the combined channel audio atdifferent speakers.

When not placing the stereo sound source in space, the device optionallydoes not combine the left audio channel and the right audio channel anddoes not apply any of an interaural time difference, an HRTF, or crosscancellation. Instead, the device produces stereo sound by producing theleft audio channel using a left loudspeaker of device and producing theright channel using a right loudspeaker of device. As a result, thedevice produces the sound in stereo and the listener perceives the audioin stereo.

Many of the techniques described below use various processes to modifysounds such that a listener perceives the sounds as coming fromparticular locations in space.

Attention is now directed towards embodiments of user interfaces (“UI”)and associated processes that are implemented on an electronic device,such as portable multifunction device 100, device 300, or device 500.

FIGS. 6A-6N illustrate exemplary techniques for transitioning betweenvisual elements, in accordance with some embodiments. The techniques inthese figures are used to illustrate the processes described below,including the processes in FIGS. 7A-7C.

FIGS. 6A-6G illustrate user 606 sitting in front of device 600 (e.g., alaptop computer) with a display 600 a, left and right loudspeakers, anda touch-sensitive surface 600 b (e.g., a touchpad). Throughout FIGS.6A-6G and 6K-6N, an additional enlarged view of touch-sensitive surface600 b of device 600 is illustrated to the right of the user to providethe reader with a better understanding of the techniques described, inparticular with respect to exemplary user inputs. Similarly, overheadview 650 is a visual depiction of the spatial organization of audiobeing produced by device 600 and is illustrated throughout FIGS. 6A-6Gto provide the reader with a better understanding of the techniques, inparticular with respect to locations from which the user 606 perceivessounds as coming from (e.g., as a result of device 600 placing the audioin space). Overhead view 650 is not part of the user interface of thedevice. Similarly, visual elements displayed outside of the displaydevice are not part of the displayed user interface, as represented bydotted outlines, but are illustrated to provide the reader with a betterunderstanding of the techniques. Similarly, visual elements displayedoutside of the display of the device are not part of the displayed userinterface, as represented by dotted outlines, but are illustrated toprovide the reader with a better understanding of the techniques.Throughout FIGS. 6A-6G, device 600 is executing: (1) a web browser 604 athat includes playback of a basketball game with game audio and gamevideo, (2) a music player 604 b that includes playback of music, and (3)video player 604 c that includes playback of show audio and show video.Audio element 654 a corresponds to audio sourced from web browser 604 a,audio element 654 b corresponds to audio sourced from music player 604b, and audio element 654 c corresponds to audio sourced from videoplayer 604 c. Throughout FIGS. 6A-6G, device 600 concurrently producesaudio sourced from each of web browser 604 a, music player 604 b, andvideo player 604 c.

At FIG. 6A, device 600 displays, on display 600 a, web browser 604 a.While displaying web browser 604 a, device 600 produces, using the leftand right loudspeakers, the game audio sourced from web browser 604 a.At FIG. 6A, while displaying web browser 604 a, device 600 does notplace the game audio of the web browser 604 a in space (e.g., device 600does not apply any of an interaural time difference, an HRTF, or crosscancellation). As a result, user 606 perceives the game audio in stereoand as being in front of the user 606, as represented in FIG. 6A by thelocation of audio element 654 a with respect to user 606 in overheadview 650. For example, the left audio channel of the game audio includesa sports commentators and does not include noise from the crowd, whilethe right audio channel includes noise from the crowd and does notinclude the sports commentators. While device 600 a displays web browser604 a, device 600 produces stereo audio using the game audio byproducing the left audio channel using the left loudspeaker of device600 a and producing the right channel using the right loudspeaker ofdevice 600 a. As a result, user 606 perceives the game audio in stereoand as being in front of the user 606, as represented in FIG. 6A by thelocation of audio element 654 a with respect to user 606 in overheadview 650. In some examples, the device would produce game audio for webbrowser 604 a in the same manner if web browser 604 a was part of acurrently accessed desktop, even if web browser 604 a was not activelybeing displayed (e.g., when a different visual element, such as a wordprocessing application, is displayed on top of web browser 604 a, thusblocking display of the web browser 604 a on display 600 a. Optionally,the audio of the various applications follow curved path 650 a whendevice 600 relocates the audio in space. In some examples, device 600 aplaces the various sound sources equidistant in space from neighboringsound sources. In some examples, device 600 a moves the various soundsources in only two axes (e.g., left-right and front-back, but notup-down).

At FIG. 6A, device 600 is not displaying music player 604 b. While notdisplaying music player 604 b, device 600 produces, using left and rightloudspeakers, music sourced from music player 604 b. At FIG. 6A, device600 places the music sourced from music player 604 b in space (e.g.,device 600 applies an interaural time difference, an HRTF, and/or crosscancellation to the music). Device 600 places the music such that theuser perceives the music as coming from a location in space that is tothe right of display 600 a (and of user 606), as illustrated by audioelement 654 b. This enables the user to recognize that the music player604 b is executing and producing audio, even when the music player 604 bis not displayed. Further, the placement of the music in space helps theuser recognize how to access the display of the music player 604 c, asdiscussed in FIGS. 6B-6G.

At FIG. 6A, device 600 is not displaying video player 604 c. While notdisplaying video player 604 c, device 600 produces, using left and rightloudspeakers, audio sourced from video player 604 c. At FIG. 6A, device600 places show audio sourced from video player 604 b in space (e.g.,device 600 applies an interaural time difference, an HRTF, and/or crosscancellation to the music). Device 600 places the show audio such thatthe user perceives the show audio as coming from a location in spacethat is further to the right of display 600 a (and user 606) than themusic from music player 604 d. This enables the user to recognize thatthe video player 604 c is executing and producing audio, even when thevideo player 604 c is not displayed. Further, the placement of the showaudio in space helps the user recognize how to access the display of thevideo player 604 c.

Additionally, device 600 optionally applies low-pass (or high-pass, orband-pass) filters to audio that correspond to applications that are offthe display (e.g., not part of a currently accessed desktop), therebyattenuating (e.g., removing) audio above certain frequency thresholdsbefore the audio is produced by the loudspeakers. As a result, the userperceives such audio as being background noise as compared to audiowhere the low-pass filter is not applied. This enables the user to moreeasily tune out the audio from certain applications, such asapplications that are not currently displayed. In some embodiments, thesame low-pass filter is applied to all audio corresponding toapplications that are not displayed. In some embodiments, differentlow-pass filters are applied to respective audio based on how far offthe display the corresponding application should be perceived by theuser. In some embodiments, device 600 optionally attenuates audio thatcorresponds to applications that are off the display (e.g., across allfrequencies of the audio).

At FIG. 6A, for example, device 600 does not apply a low-pass filter forthe game audio sourced from web browser 604 a, device 600 applies afirst low-pass filter with a first cutoff frequency for music sourcedfrom music player 604 b, and device 600 applies a second low-pass with asecond cutoff frequency (lower than the first cutoff frequency) for showaudio sourced from video player 604 c. Thus, at FIG. 6A, device 600concurrently produces audio from each of web browser 604 a, music player604 b, and video player 604 c.

At FIGS. 6B-6C, device 600 receives a left-swipe user input 610 a attouch-sensitive surface 600 b. In response to receiving the left-swipeuser input 610 a, as illustrated in FIGS. 6B-6C, device 600 transitionsdisplay of web browser 604 a off display 600 a by sliding web browser604 a to the left and transitions display of music player 604 b ontodisplay 600 a by sliding music player 604 b to the left. Further inresponse to receiving the left-swipe user input 610 a, as illustrated inoverhead view 650 of FIGS. 6B-6C, device 600 changes the locations inspace from which the user perceives audio from correspondingapplications.

At FIG. 6D, device 600 is not displaying web browser 604 a. While notdisplaying web browser 604 a, device 600 places, using left and rightloudspeakers, audio sourced from web browser 604 a in space (e.g.,device 600 applies an interaural time difference, an HRTF, and/or crosscancellation to the audio) such that the user perceives the game audioas coming from a location in space that is to the left of display 600 a(and user 606). This enables the user to recognize that the web browser604 a is executing and producing audio, even when the web browser 604 ais not displayed. Further, the placement of the game audio in spacehelps the user recognize how to access the display of web browser 604 a(e.g., using a swipe-right user input).

At FIG. 6D, device 600 displays, on display 600 a, music player 604 b.While displaying music player 604 b, device 600 produces, using the leftand right loudspeakers, the audio sourced from music player 604 b. AtFIG. 6D, while displaying music player 604 b, device 600 does not placethe music sources from music player 604 b in space (e.g., device 600does not apply any of an interaural time difference, an HRTF, or crosscancellation). As a result, user 606 perceives the music in stereo andas being in front of the user 606, as represented in overhead view 650of FIG. 6D by the location of audio element 654 c with respect to user606.

At FIG. 6D, device 600 is not displaying video player 604 c. While notdisplaying video player 604 c, device 600 places, using left and rightloudspeakers, audio sourced from video player 604 c in space (e.g.,device 600 applies an interaural time difference, an HRTF, and/or crosscancellation to the audio) such that the user perceives the audiosourced from video player 604 c as coming from a location in space thatis to the right of display 600 a (and user 606), and not as far right aspreviously perceived by the user in FIG. 6A. This enables the user torecognize that the video player 604 c is executing and producing audio,even when video player 604 c is not displayed. Further, the placement ofthe show audio in space helps the user recognize how to access thedisplay of video player 604 c (e.g., using a swipe-left user input).

At FIG. 6D, for example, device 600 does not apply a low-pass filter forthe music sourced from music player 604 b, device 600 applies the firstlow-pass filter with the first cutoff frequency for game audio sourcedfrom web browser 604 a, and device 600 applies the first low-pass withthe first cutoff frequency for show audio sourced from video player 604c. Thus, at FIG. 6D, device 600 concurrently produces audio from each ofweb browser 604 a, music player 604 b, and video player 604 c.

At FIGS. 6E-6F, device 600 receives a right-swipe user input 610 b attouch-sensitive surface 600 b. In response to receiving the right-swipeuser input 610 b, as illustrated in FIGS. 6E-6F, device 600 transitionsdisplay of web browser 604 a onto display 600 a by sliding web browser604 a to the right and transitions display of music player 604 b off ofdisplay 600 a by sliding music player 604 b to the right. Further inresponse to receiving right-swipe user input 610 b, as illustrated inoverhead view 650 of FIGS. 6E-6F, device 600 changes the locations inspace from which the user perceives audio from correspondingapplications. In this example, the device modifies the audio such thatthe user perceives them as described in FIG. 6A.

FIG. 6G illustrates an example corresponding to FIG. 6A. In FIG. 6G, theuser is listening to the audio produced by device 600 a usingheadphones. As a result, rather than perceiving the game audio of webbrowser 604 a as being in front of the user, the user perceives the gameaudio as being produced in the user head. Optionally, the audio of thevarious applications follow straight path 650 b when device 600relocates the audio in space. In some examples, device 600 a places thevarious sound sources equidistant in space from neighboring soundsources. In some examples, device 600 a moves the various sound sourcesin only two axes (e.g., left-right and front-back, but not up-down).

FIGS. 6H-6J illustrates device 660 (e.g., a mobile phone) with a display660 a (e.g., a touchscreen), a touch-sensitive surface 660 b (e.g., partof the touchscreen), connected (e.g., wirelessly, wired) to headphones.In this example, user 606 is listening to device 660 using theheadphones.

Overhead view 670 is a visual depiction of the spatial organization ofaudio being produced by device 660 and is illustrated throughout FIGS.6H-6J to provide the reader with a better understanding of thetechniques, in particular with respect to locations from which the user606 perceives sounds as coming from (e.g., as a result of device 660placing the audio in space). Overhead view 670 is not part of the userinterface of device 660. Similarly, visual elements displayed outside ofthe display device are not part of the displayed user interface, asrepresented by dotted outlines, but are illustrated to provide thereader with a better understanding of the techniques. Throughout FIGS.6H-6J, device 660 is executing a music player that includes playback ofmusic with corresponding album art.

Audio element 674 a corresponds to track 1 audio sourced from the musicplayer, audio element 674 b corresponds to track 2 audio sourced fromthe music player, audio element 674 c corresponds to track 3 audiosourced from the music player, and audio element 674 d corresponds totrack 4 audio sourced from the music player.

At FIG. 6H, device 660 does not display, on display 660 a, album art 664a for track 1. While not displaying album art 664 a for track 1, device660 produces, using the left and right speakers of the headphones, audioof track 1 by placing the audio of track 1 in space (e.g., device 660applies an interaural time difference, an HRTF, and/or crosscancellation) such that the user perceives the audio as coming from afirst point in space (e.g., to the left of the user, to the left of thedevice), as represented in FIG. 6H by the location of audio element 670a with respect to user 606 in overhead view 670. In this example, device660 additionally modifies the audio for track 1 by attenuating the audioand/or applying a low-pass (or high-pass, or band-pass) filter to theaudio. In some examples, device 660 does not produce the audio of track1 when the corresponding album art is off the display.

At FIG. 6H, device 660 displays, on display 660 a, album art 664 b fortrack 2. While displaying album art 664 b for track 2, device 600produces, using the left and right headphones, audio of track 2 byplacing the audio of track 2 in space (e.g., device 600 applies aninteraural time difference, an HRTF, or cross cancellation) such thatthe user perceives the audio as coming from a second point in space(e.g., different from the first point in space, to the right of thefirst point in space, in front of the user, at a location correspondingto device 660), as represented in FIG. 6H by the location of audioelement 670 b with respect to user 606 in overhead view 670. In thisexample, device 660 does not modify the audio for track 2 by attenuatingthe audio or applying a low-pass (or high-pass, or band-pass) filter tothe audio.

At FIG. 6H, device 660 does not display, on display 660 a, album art 664c for track 3. Device 660 also does not produce, using the left or rightspeakers of the headphones, audio of track 3.

At FIGS. 6I-6J, device 660 receives left-swipe user input 666 attouch-sensitive surface 660 a. In response to receiving the left-swipeuser input 666, as illustrated in FIGS. 6I-6J, device 660 transitionsdisplay of album art 664 b off of display 660 a by sliding album art 664b to the left and transitions display of album art 664 c onto display660 a by sliding the album art 664 c to the left. Further in response toreceiving left-swipe user input 666, device 660 begins producing audiofor track 3 (concurrently with track 2) and changes the locations inspace from which the user perceives audio from track 2 and track 3, asillustrated in overhead view 670 of FIGS. 6I-6J. In some examples,producing audio for track 3 in response to receiving the left-swipe userinput 666 includes skipping a predetermined amount of time of the audio(e.g., the first 0.5 seconds of track 2). This provides the user with asense that track 3 was previously playing, even when device 660 was notpreviously producing audio for track 3.

At FIG. 6J, device 660 ceases to produce audio for track 1. Device 660produces audio for track 2, using the left and right speakers of theheadphones, by placing the audio of track 2 in space (e.g., device 660applies an interaural time difference, an HRTF, and/or crosscancellation) such that the user perceives the audio as coming from thefirst point in space (e.g., to the left of the user, to the left of thedevice), as represented in FIG. 6J by the location of audio element 670b with respect to user 606 in overhead view 670. In this example, device660 additionally modifies the audio for track 2 by attenuating the audioand/or applying a low-pass (or high-pass, or band-pass) filter to theaudio. In some examples, device 660 fades out the audio of track 2(ceasing to produce audio) as the corresponding album art moves off thedisplay.

At FIG. 6J, device 660 displays, on display 660 a, album art 664 c fortrack 3. While displaying album art 664 b for track 3, device 600produces, using the left and right headphones, audio of track 3 byplacing the audio of track 3 in space (e.g., device 600 applies aninteraural time difference, an HRTF, or cross cancellation) such thatthe user perceives the audio as coming from the second point in space(e.g., different from the first point in space, to the right of thefirst point in space, in front of the user, at a location correspondingto device 660), as represented in FIG. 6H by the location of audioelement 670 c with respect to user 606 in overhead view 670. In thisexample, device 660 does not modify the audio for track 3 by attenuatingthe audio or applying a low-pass (or high-pass, or band-pass) filter tothe audio.

As a result, user 606 perceives the music as passing in front of theuser as the user swipes through various album art.

FIGS. 6K-6N illustrate user 606 sitting in front of device 600 (e.g., alaptop computer) with a display 600 a, left and right loudspeakers, anda touch-sensitive surface 600 b (e.g., a touchpad). Throughout FIGS.6K-6N, an additional enlarged view of touch-sensitive surface 600 b ofdevice 600 is illustrated to the right of the user to provide the readerwith a better understanding of the techniques described, in particularwith respect to user inputs (or lack thereof). Similarly, overhead view680 is a visual depiction of the spatial organization of audio beingproduced by device 600 and is illustrated throughout FIGS. 6K-6N toprovide the reader with a better understanding of the techniques, inparticular with respect to locations from which the user 606 perceivessounds as coming from (e.g., as a result of device 600 placing the audioin space). Overhead view 680 is not part of the user interface of device600. Similarly, visual elements displayed outside of the display deviceare not part of the displayed user interface, as represented by dottedoutlines, but are illustrated to provide the reader with a betterunderstanding of the techniques.

At FIG. 6K, a music player 604 b is playing music. While displayingmusic player 604 a, device 600 produces, using the left and rightspeakers, audio sourced from music player 604 a. For example, device 600does not place the audio sourced from music player 604 a in space (e.g.,device 660 does not apply any of an interaural time difference, an HRTF,or cross cancellation). As a result, user 606 perceives stereo music asbeing in front of user 606, as represented in FIG. 6K by the location ofaudio element 680 a with respect to user 606 in overhead view 680.Throughout FIGS. 6K-6N, audio element 680 a corresponds to audio beingprovided by music player 604 b.

At FIG. 6L, device 600 receives a notification (e.g., a messagenotification received, via a network connection). In response toreceiving the notification (and without receiving user input), device600 transitions to producing, using the left and right speakers, themusic sourced from music player 604 a by placing the music in space(e.g., device 600 applies an interaural time difference, an HRTF, orcross cancellation) such that the user perceives the audio as comingfrom a point in space that is to the left of device 600, as representedin FIGS. 6L-6M by the locations of audio element 680 a with respect touser 606 in overhead view 680. Device 600 maintains display of musicplayer 604 a on display 600 a. In some examples, device 600 alsodisplays the notification in response to receiving the notification.Throughout FIGS. 6K-6N, audio element 680 b corresponds to audio beingprovided by the notification.

In further response to receiving the notification (and without receivinguser input), device 600 transitions from not producing audio for thenotification to producing, using the left and right speakers, audio forthe notification by placing the audio for the notification in space(e.g., device 600 applies an interaural time difference, an HRTF, orcross cancellation) such that the user perceives the audio for thenotification as coming from a point in space that is to the right ofdevice 600, as represented in FIG. 6L by the location of audio element680 b with respect to user 606 in overhead view 680. In some examples,device 600 emphasizes the audio for the notification by ducking themusic sourced from music player 604 a. For example, device 600attenuates the music sourced from music player 604 a while producingaudio for the notification. Device 600 then transitions to producing theaudio for the notification without placing the audio in space (e.g.,device 600 does not apply any of an interaural time difference, an HRTF,or cross cancellation), as represented in FIG. 6M by the location ofaudio element 680 b with respect to user 606 in overhead view 680.

Subsequently, device 600 produces, using the left and right speakers,audio sourced from music player 604 a without placing the audio sourcedfrom music player 604 a in space (e.g., device 600 does not apply any ofan interaural time difference, an HRTF, or cross cancellation), asillustrated in FIG. 6N.

In some examples, devices 600 and 660 include a digital assistant thatproduces audio feedback, such as returning the results of a query byspeaking the results. In some examples, devices 600 and 660 produceaudio for the digital assistant by placing the audio for the digitalassistant at a location in space (e.g., over the right shoulder of theuser) such that the user perceives the digital assistant as remainingstationary in space even when other audio moves in space. In someexamples, devices 600 and 660 emphasize the audio for the digitalassistant by ducking one or more (or all) other audio.

FIGS. 7A-7C is a flow diagram illustrating a method for transitioningbetween visual elements using an electronic device in accordance withsome embodiments. Method 700 is performed at a device (e.g., 100, 300,500, 600, 660) with a display, wherein the electronic device is operablyconnected with two or more speakers (e.g., left and right speakers, leftand right headphones, left and right earphones, left and right earbuds).Some operations in method 700 are, optionally, combined, the orders ofsome operations are, optionally, changed, and some operations are,optionally, omitted.

As described below, method 700 provides an intuitive way fortransitioning between visual elements. The method reduces the cognitiveburden on a user for transitioning between visual elements, therebycreating a more efficient human-machine interface. For battery-operatedcomputing devices, enabling a user to transitioning between visualelements faster and more efficiently conserves power and increases thetime between battery charges.

The electronic device displays (702), at a first location on thedisplay, a first visual element (e.g., 604 a, a video playback window,album art, of a first application).

The electronic device accesses (704) first audio (e.g., 654 a, fromfirst source audio) corresponding to the first visual element (e.g.,audio of the video in the playback window, audio of the song from thealbum corresponding to the album art, audio generated by, or receivedfrom, the first application).

In accordance with some embodiments, the electronic device accesses(706) second audio (e.g., 654 b, from second source audio) correspondingto a second visual element (e.g., 604 b).

While (708) displaying, at the first location (e.g., a location on thedisplay that is substantially centered horizontally on the display) onthe display, the first visual element (e.g., 604 a), the electronicdevice produces audio, at the two or more speakers using the first audio(e.g., 654 a), in a first mode (e.g., without modifying the first audio,without apply any of an interaural time difference, an HRTF, or crosscancellation, 654 a as depicted in FIG. 6A).

In accordance with some embodiments, the first mode is configured (712)such that audio produced using the first mode is perceived by the useras being produced from a first direction (and, optionally, location)that corresponds to (e.g., aligned with) the display.

While (708) displaying, at the first location (e.g., a location on thedisplay that is substantially centered horizontally on the display) onthe display, the first visual element (e.g., 604 a), the electronicdevice produces audio (e.g., a discrete audio output or a combined audiooutput that includes a component based on the second audio), at the twoor more speakers using the second audio (e.g., 654 b), in a third mode(e.g., apply an interaural time difference, an HRTF, and/or crosscancellation, 654 b as depicted in FIG. 6A) different from the firstmode and a second mode. The third mode is configured such that audioproduced in the third mode is perceived by the user as being producedfrom a direction (and optionally, location) that is off (e.g., notaligned with, to the right of) the display (e.g., modifying the sourceaudio before producing the audio such that the audio is perceived by auser as being produced from a direction that is to the right of thedisplay or user). In some examples, the first mode places audio in frontof the user or display, the second more places audio to the left of theuser or display, and the third mode places audio to the right of theuser or display.

While (708) displaying, at the first location (e.g., a location on thedisplay that is substantially centered horizontally on the display) onthe display, the first visual element (e.g., 604 a), the electronicdevice forgoes (716) displaying, on the display, a second visual element(e.g., 604 b at FIG. 6A, a second video playback window, second albumart, of a second application) that corresponds to the second audio(e.g., 654 b, from second source audio) (e.g., audio of the video in theplayback window, audio of the song from the album corresponding to thealbum art, audio generated by, or received from, the secondapplication).

While (708) displaying, at the first location (e.g., a location on thedisplay that is substantially centered horizontally on the display) onthe display, the first visual element (e.g., 604 a), the electronicdevice receives (718) first user input (e.g., 610 a, a swipe input ontouch-sensitive surface 600 b).

In response (720) to receiving the first user input (e.g., 610 a), theelectronic device transitions (e.g., by sliding) display of the firstvisual element (e.g., 604 a at FIG. 6B) from the first location on thedisplay to the first visual element (e.g., 604 a at FIG. 6C) not beingdisplayed on the display (e.g., by sliding off an edge of the display(e.g., a left edge)).

Further in response (720) to receiving the first user input (e.g., 610a) and while not displaying, on the display, the first visual element(e.g., 604 a at FIG. 6C), the electronic device produces (724) audio, atthe two or more speakers, using the first audio (e.g., 654 a) in thesecond mode that is different from the first mode. The second mode isconfigured such that audio produced in the second mode is perceived bythe user as being produced from a direction (and optionally, location)that is off (e.g., not aligned with, to the left of) the display (e.g.,modifying the source audio before producing the audio such that theaudio is perceived by a user as being produced from a direction that isoff the display in a direction corresponding to the last displayedposition of the first visual element (e.g., to the left of the displayor user), apply an interaural time difference, an HRTF, and/or crosscancellation, 654 a as depicted in FIG. 6C). Producing audio relating tocontent with varying characteristics enables the user to visualize wherethe content is in relation to the user without requiring display of thecontent. This enables the user to quickly and easily recognize whatinputs are required to access the content (e.g., to cause display of thecontent). Producing audio with varying characteristics also provides theuser with contextual feedback about the placement of different content.Providing improved audio feedback to the user enhances the operabilityof the device and makes the user-device interface more efficient (e.g.,by helping the user to provide proper inputs) which, additionally,reduces power usage and improves battery life of the device by enablingthe user to use the device more quickly and efficiently.

In some examples, the volume of audio produced using the first mode ishigher than the volume of audio produced using the second mode or usingthe third mode. In some examples, the volume of audio produced using thesecond mode is the same as the volume of audio produced using the firstmode.

In some examples, a frequency filter, such as a low-pass filter, ahigh-pass filter, or a bandpass filter, is not applied to audio producedin the first mode (e.g., when the audio is perceived as being centered,such as in front of the user). In some examples, a first frequencyfilter, such as a low-pass filter, a high-pass filter, or a bandpassfilter, is applied to audio produced using the first mode. In someexamples, a second frequency filter, such as a low-pass filter, ahigh-pass filter, or a bandpass filter, is applied to audio producedusing the second mode. In some examples, a third frequency filter, suchas a low-pass filter, a high-pass filter, or a bandpass filter, isapplied to audio produced using the third mode. In some examples, thesecond frequency filter is the same as the third frequency filter. Insome examples, frequency filters are applied to audio produced using thesecond mode and the third mode, but not to audio produced using thefirst mode.

In accordance with some embodiments, while displaying, at the firstlocation on the display, the first visual element (e.g., 604 a in FIG.6A, a video playback window, album art, of a first application), theelectronic device forgoes displaying, on the display, a second visualelement (e.g., 604 b at FIG. 6A, a second video playback window, secondalbum art, of a second application) that corresponds to second audio(e.g., 654 b, from second source audio) (e.g., audio of the video in theplayback window, audio of the song from the album corresponding to thealbum art, audio generated by, or received from, the secondapplication). Not displaying content saves display space and allows thedevice to provide the user with other visual feedback on the display.Providing improved visual feedback to the user enhances the operabilityof the device and makes the user-device interface more efficient (e.g.,by helping the user to provide proper inputs and reducing user mistakeswhen operating/interacting with the device) which, additionally, reducespower usage and improves battery life of the device by enabling the userto use the device more quickly and efficiently.

In accordance with some embodiments, further in response (720) toreceiving the first user input (e.g., 610 a), the electronic devicetransitions (726) (e.g., by sliding) display of the second visualelement (e.g., 604 b) from not being displayed on the display to afourth location on the display (e.g., 604 b at FIG. 6C, same as thefirst location) (e.g., by sliding the second visual element onto thedisplay from an edge (such as the right edge) of the display).

In accordance with some embodiments, further in response (720) toreceiving the first user input (e.g., 610 a), concurrent with producingaudio using the first audio (e.g., 654 a at FIG. 6C) in the second mode,the electronic device produces (728) audio, at the two or more speakers,using the second audio (e.g., 654 b at FIG. 6C) in the first mode (e.g.,without modifying the second audio). In other examples, the second audiois produced in a mode different from the first mode.

In accordance with some embodiments, the second mode is configured suchthat audio produced using the second mode is perceived by the user asbeing produced from a second direction (e.g., different from the firstdirection). In accordance with some embodiments, the third mode isconfigured such that audio produced using the third mode is perceived bythe user as being produced from a third direction different from thesecond direction (and, optionally, different from the first direction).Thus, optionally, a perceived location of source for audio producedusing the various modes differs.

In accordance with some embodiments, subsequent to displaying, at thefirst location (e.g., a location on the display that is substantiallycentered horizontally on the display) on the display, the first visualelement (e.g., 604 a at FIG. 6A) and prior to the first visual elementnot being displayed on the display (e.g., 604 a at FIG. 6C), theelectronic device displays, at a second location (e.g., a location onthe display that is to the left of the first location on the display, alocation on the display that is not substantially centered horizontallyon the display, a location on the display that is adjacent to an edge(e.g., a left edge) of the display) on the display, the first visualelement (e.g., 604 a at FIG. 6B). In accordance with some embodiments,subsequent to displaying, at the first location (e.g., a location on thedisplay that is substantially centered horizontally on the display) onthe display, the first visual element (e.g., 604 a at FIG. 6A) and priorto the first visual element not being displayed on the display (e.g.,604 a at FIG. 6C), while displaying the first visual element (e.g., 604a at FIG. 6B) at the second location on the display, the electronicdevice produces audio, at the two or more speakers, using the firstaudio (e.g., 654 a at FIG. 6B) in a fourth mode that is different fromthe first mode, the second mode, and the third mode (e.g., modifying thesource audio before producing the audio such that the audio is perceivedby a user as being produced from a direction that is different from thelocation at which the audio was perceived when produced in the firstmode, such as at or near the left side of the display).

In accordance with some embodiments, the first mode does not include amodification of an interaural time difference of audio. In someexamples, audio produced in the first mode (e.g., 654 a at FIG. 6A) isnot modified using any of an HRTF, an interaural time different ofaudio, or cross cancellation. In some examples, while the first visualelement is displayed, the electronic device plays the first audio usinga HRTF configured such that the first audio is perceived as being infront of the user, such as within a range of 10 degrees left and 10degrees right of the direction the user is facing. In some examples,while displaying, on the display, the first visual element, theelectronic device produces the first audio using an HRTF that modifiesthe interaural time difference of the first audio by less then a firstpredetermined amount (e.g., minimal changes).

In accordance with some embodiments, the second mode includes amodification of an interaural time difference of audio. In someexamples, the second mode includes a first degree modification of theinteraural time difference of audio and the second mode includes asecond degree modification, larger than the first degree, of theinteraural time difference of audio. In some examples, the third modeincludes a modification of an interaural time difference of audio. Insome examples, audio produced in the second mode (e.g., 654 b at FIG.6C) is modified using one or more of an HRTF, an interaural timedifferent of audio, and cross cancellation. In some examples, audioproduced in the third mode (e.g., 654 b at FIG. 6A) is modified usingone or more of an HRTF, an interaural time different of audio, and crosscancellation. Producing audio relating to content with varyingcharacteristics enables the user to visualize where the content is inrelation to the user without requiring display of the content. Thisenables the user to quickly and easily recognize what inputs arerequired to access the content (e.g., to cause display of the content).Producing audio with varying characteristics also provides the user withcontextual feedback about the placement of different content. Providingimproved audio feedback to the user enhances the operability of thedevice and makes the user-device interface more efficient (e.g., byhelping the user to provide proper inputs) which, additionally, reducespower usage and improves battery life of the device by enabling the userto use the device more quickly and efficiently.

In accordance with some embodiments, modification of the interaural timedifference of audio includes: combining a first channel audio (e.g., aright channel) of the audio and a second channel audio (e.g., a leftchannel) of the audio to form a combined channel audio, updating thesecond channel audio to include the combined channel audio at a firstdelay (e.g., 0 ms delay, less than a delay amount), updating the firstchannel audio to include the combined channel audio at a second delay(e.g., a 100 ms delay, more than the delay amount) different from thefirst delay.

In some examples, modifying the interaural time difference of audioincludes introducing a time delay to a first channel audio (e.g., aright channel) without introducing a time delay to the second channelaudio (e.g., a left channel) that is different from the first audiochannel.

In accordance with some embodiments, in response to beginning to receive(e.g., beginning to detect) the first user input (e.g., a swipe input),the electronic device transitions from not producing audio using secondaudio (e.g., from second source audio) (e.g., audio of the video in theplayback window, audio of the song from the album corresponding to thealbum art, audio generated by, or received from, the second application)that corresponds to a second visual element (e.g., a second videoplayback window, second album art, of a second application) toproducing, at the two or more speakers, audio using second audio thatcorresponds to the second visual element. For example, there is no audiobeing produced at the speakers using the second audio before the firstinput is received. When the beginning of the first input is detected (orafter a portion of the first input is detected, or after the first inputis detected), the device produces, at the two or more speakers, audiousing second audio that corresponds to the second visual element. Insome examples, the second audio is an audio file (e.g., a song) andtransitioning to producing audio using the second audio includesforgoing producing audio using a first predetermined portion (e.g., thefirst 0.1 seconds) of the second audio. For example, this provides aneffect that the audio was playing before the audio is heard by the user.

In accordance with some embodiments, producing audio using the secondmode (and, optionally, third mode) includes one or more of attenuatingthe audio, applying a high-pass filter to the audio, applying a low-passfilter to the audio, and changing a volume balance among the two or morespeakers. Optionally, producing audio using the one or more of:attenuating the audio, applying a high-pass filter to the audio,applying a low-pass filter to the audio, and changing a volume balanceamong the two or more speakers. Producing audio relating to content withvarying characteristics enables the user to visualize where the contentis in relation to the user without requiring display of the content.This enables the user to quickly and easily recognize what inputs arerequired to access the content (e.g., to cause display of the content).Producing audio with varying characteristics also provides the user withcontextual feedback about the placement of different content. Providingimproved audio feedback to the user enhances the operability of thedevice and makes the user-device interface more efficient (e.g., byhelping the user to provide proper inputs) which, additionally, reducespower usage and improves battery life of the device by enabling the userto use the device more quickly and efficiently.

In some examples, producing audio using the second mode (or the thirdand fourth modes) includes applying crosstalk cancelation technique tothe audio such that the audio is configured to be perceived by the useras coming from a particular direction. In some examples, producing audiousing the third mode includes applying crosstalk cancelation techniqueto the audio such that the audio is configured to be perceived as comingfrom a particular direction. In some examples, producing audio using thefirst mode does not include applying a crosstalk cancelation techniqueto the audio.

Note that details of the processes described above with respect tomethod 700 (e.g., FIGS. 7A-7C) are also applicable in an analogousmanner to the methods described below. For example, methods 900, 1200,1400, and 1500 optionally include one or more of the characteristics ofthe various methods described above with reference to method 700. Forexample, the same or similar techniques are used to place audio inspace. For another example, the same audio sources may be used in thevarious techniques. For yet another example, currently playing audio ineach of the various methods can be manipulated using the techniquesdescribed in other methods. For brevity, these details are not repeatedbelow.

FIGS. 8A-8K illustrate exemplary techniques for previewing audio, inaccordance with some embodiments. The techniques in these figures areused to illustrate the processes described below, including theprocesses in FIGS. 9A-9C.

FIGS. 8A-8K illustrate device 800 (e.g., a mobile phone) with a display,a touch-sensitive surface, and left and right speakers (e.g.,headphones). Overhead view 850 is a visual depiction of the spatialorganization of audio being produced by device 800 and is illustratedthroughout FIGS. 8A-8K to provide the reader with a better understandingof the techniques, in particular with respect to locations from whichthe user 856 perceives sounds as coming from (e.g., as a result ofdevice 800 placing audio in space). Overhead view 850 is not part of theuser interface of device 800. In some examples, the techniques describedbelow enable users to more easily and efficiently preview and selectmusic for playback.

At FIG. 8A, device 800 displays a music player 802 for playing music.Music player 802 includes a plurality of affordances 804, each of whichcorrespond to a different song that can be played using device 800. Asillustrated in overhead view 850, device 800 is not playing any audio.

At FIG. 8B, device 800 detects a tap-and-hold input 810 a on affordance804 a for track 3. As illustrated in overhead view 850, device 800 isnot playing any audio.

At FIG. 8C, in response to detecting input 810 a on affordance 804 a andwhile continuing to detecting input 810 a on affordance 804 a, device800 updates the plurality of affordances 804 to differentiate affordance804 a for track 3. In the example of FIG. 8C, device 800 blurs out theplurality of affordance 804 other than the selected affordance 804 a fortrack 3. This indicates to the user that the song corresponding toaffordance 804 a will be previewed.

For example, previews are limited to a predetermined audio playbackduration (e.g., less then the duration of the song). After thepredetermined audio playback duration is reached during playback of asong, the device ceases to play that song. In some examples, afterceasing to play the song, the device proceeds to providing a preview ofa different song. In some examples, after ceasing to play the song, thedevice proceeds to providing another preview of the same song (e.g.,loop the same portion of the song).

As illustrated in overhead view 850 of FIG. 8C, in response to detectinginput 810 a on affordance 804 a and while continuing to detecting input810 a on affordance 804 a, device 800 produces, using the two or morespeakers, a preview of audio of track 3 by placing the audio of track 3in space (e.g., device 800 applies an interaural time difference, anHRTF, and/or cross cancellation to the music). Device 800 places theaudio of track 3 such that the user perceives the music as coming from alocation in space that is to the left of the user 856 (or device 800),as illustrated by audio element 850 a in overhead view 850 of FIG. 8C.At FIGS. 8C-8D, device 800 continues to detect input 810 a on affordance804 a and updates the location in space of the audio of track 3 at whichthe user perceives the music such that the user perceives the music asmoving toward the user.

At FIG. 8D, device 800 continues to produce the audio for track 3 buthas stopped placing the audio in space and, as a result, the userperceives the audio as being in the user's head, as illustrated by audioelement 850 a in overhead view 850 of FIG. 8D. For example, at FIG. 8D,device 800 produces audio of track 3, using the left and right speakers,without placing the audio (e.g., device 800 does not apply any of aninteraural time difference, an HRTF, or cross cancellation).

Device 800 continues to play the preview of track 3 for the user until(1) the predetermined audio playback duration is reached, (2) thedevices detects movement of the input 810 a on the touch-sensitivesurface to an affordance corresponding to a different song, or (3) thedevice detects lift-off of the input 810 a.

At FIG. 8E, device 800 detects movement of input 810 a from affordance804 a to affordance 804 b (without detecting a lift-off of input 810 a).Note that device 800 does not scroll (or otherwise move) the pluralityof affordances 804 in response to detecting the movement of input 810 a.In response to detecting the input at affordance 804 b, device 800updates the visual aspects of the device and the spatial placement ofthe audio. Device 800 blurs out affordance 804 a for track 3 and unblursaffordance 804 b for track 4. Device 800 also transitions to producingaudio of track 3, using the left and right speakers, by placing theaudio in space (e.g., device 800 applies an interaural time difference,an HRTF, and/or cross cancellation), such that the user perceives theaudio as leaving the user's head and moving off to the right of theuser, as illustrated by audio element 850 a in overhead view 850 ofFIGS. 8E-8F. Device 800 also optionally begins attenuating the audio oftrack 3 and then ceasing to produce the audio of track 3, as illustratedby audio element 850 a no longer being illustrated in overhead view 850of FIG. 8G. Further in response to detecting the input at affordance 804b, device 800 produces a preview of audio of track 4 by placing theaudio in space (e.g., device 800 applies an interaural time difference,an HRTF, and/or cross cancellation), such that the user perceives theaudio of track 4 as coming from the left of the user and moving into thehead of the user, as illustrated by audio element 850 b in overhead view850 of FIGS. 8E-8G. As before, the preview is limited to thepredetermined audio playback duration (e.g., less then the duration ofthe song). After the predetermined audio playback duration is reached,the device ceases to play the song.

At FIGS. 8F-8G, device 800 produces audio of track 4, using the left andright speakers, without placing the audio (e.g., device 800 does notapply any of an interaural time difference, an HRTF, or crosscancellation). For example, as a result of not placing the audio inspace, a user of device 800 wearing headphones perceives the audio asbeing in the head of the user, as illustrated by audio element 850 b inoverhead view 850 of FIGS. 8F-8G.

At FIG. 8H, device 800 detects lift-off of input 810 a. In response todetecting lift-off of input 810 a, device 800 transitions to producingaudio of track 4, using the left and right speakers, by placing theaudio in space (e.g., device 800 applies an interaural time difference,an HRTF, and/or cross cancellation), such that the user perceives theaudio as leaving the user's head and moving off to the right of theuser, as illustrated by audio element 850 b in overhead view 850 of FIG.8H. In response to detecting lift-off of input 810 a, device 800 ceasesto blur out the plurality of affordances, as illustrated in FIG. 8H.Further in response to detecting lift-off of input 810 a, device 800optionally begins attenuating the audio of track 4 and then ceasing toproduce the audio of track 4, as illustrated by audio element 850 b nolonger being illustrated in overhead view 850 of FIG. 8I.

At FIG. 8J, device 800 detects a tap input 810 b on affordance 804 c fortrack 6. At FIG. 8K, as illustrated in overhead view 850, device 800begins produces, using the two or more speakers, audio of track 6without placing the audio of track 6 in space, as illustrated by audioelement 850 c in overhead view 850 of FIG. 8J. As a result, the userperceives the audio as being in the user's head. For example, at FIG.8J, device 800 produces stereo audio of track 6, using the left andright speakers, without placing the audio (e.g., device 800 does notapply any of an interaural time difference, an HRTF, or crosscancellation). Device 800 does not blur out any of the plurality ofaffordances 804 in response to detecting tap input 810 b. Device 800also optionally updates affordance 804 c to include media controlsand/or additional information about the track. Track 6 continues to playuntil reaching the end of the track without playback being limited to apreview of the predetermined audio playback duration.

In some examples, device 800 includes a digital assistant that producesaudio feedback, such as returning the results of a query by speaking theresults. In some examples, device 800 produces audio for the digitalassistant by placing the audio for the digital assistant at a locationin space (e.g., over the right shoulder of the user) such that the userperceives the digital assistant as remaining stationary in space evenwhen other audio moves in space. In some examples, device 800 emphasizesthe audio for the digital assistant by ducking one or more (or all)other audio.

FIGS. 9A-9C is a flow diagram illustrating a method for previewing audiousing an electronic device in accordance with some embodiments. Method900 is performed at a device (e.g., 100, 300, 500, 800) with a displayand a touch-sensitive surface. The electronic device is operablyconnected with two or more speakers (e.g., left and right speakers, leftand right headphones, left and right earphones, left and right earbuds).Some operations in method 900 are, optionally, combined, the orders ofsome operations are, optionally, changed, and some operations are,optionally, omitted.

As described below, method 900 provides an intuitive way for previewingaudio. The method reduces the cognitive burden on a user for previewingaudio, thereby creating a more efficient human-machine interface. Forbattery-operated computing devices, enabling a user to previewing audiofaster and more efficiently conserves power and increases the timebetween battery charges.

The electronic device displays (902), on the display, a list (e.g., in acolumn) of a plurality of media elements (e.g., 804). Each media element(e.g., 804 a-804 c) (or at least two media elements) of the plurality ofmedia elements corresponds to a respective media file (e.g., an audiofile, a song, a video file). In some examples, the respective mediafiles are all different from each other.

The electronic device detects (904), using the touch-sensitive surface,a user contact (e.g., 810 a, a touch-and-hold user input, a touch inputthat is sustained for greater than a predetermined period of time thatis more than 0 seconds) at a location corresponding to a first mediaelement (e.g., 804 a).

In response (906) to detecting the user contact (e.g., 810 a at FIGS.8B-8C) at the location corresponding to the first media element (e.g.,804 a) and in accordance with the user contact (e.g., 810 a) including atouch-and-hold input (e.g., as determined by the electronic device), theelectronic device produces, using the two or more speakers, audio (e.g.,850 a) using a first audio file that corresponds to the first mediaelement without exceeding a predetermined audio playback duration. Forexample, the audio plays for a maximum of 5 seconds. For example, thedevice produces a preview of the audio. In some examples, thepredetermined audio playback duration is less than the duration of theaudio file.

Further in response (906) to detecting the user contact (e.g., 810 a atFIGS. 8B-8C) at the location corresponding to the first media element(e.g., 804 a) and in accordance with the user contact (e.g., 810 a)including a touch-and-hold input (e.g., as determined by the electronicdevice) and while (910) the user contact (e.g., 810 a) remains (withouta lift-off event) at the location corresponding to the first mediaelement (e.g., 804 a), and in accordance with the predetermined audioplayback duration period not being exceeded, the electronic devicecontinues (912) to produce, using the two or more speakers, audio (e.g.,850 a) using the first audio file.

Further in response (906) to detecting the user contact (e.g., 810 a atFIGS. 8B-8C) at the location corresponding to the first media element(e.g., 804 a) and in accordance with the user contact (e.g., 810 a)including a touch-and-hold input (e.g., as determined by the electronicdevice) and while (910) the user contact (e.g., 810 a) remains (withouta lift-off event) at the location corresponding to the first mediaelement (e.g., 804 a), and in accordance with the predetermined audioplayback duration period being exceeded, the electronic device ceases(914) to produce, using the two or more speakers, audio (e.g., 850 a)using the first audio file (and, optionally, without beginning toproduce audio using a different audio file).

The electronic device detects (916), using the touch-sensitive surface,movement (e.g., 810 a at FIGS. 8D-8E, downward movement toward thebottom of the display and away from the top of the display) of the usercontact from the location that corresponds to the first media element(e.g., 804 a) to a location that corresponds to a second media element(e.g., 804 b).

In response (918) to detecting the user contact (e.g., 810 a at FIG. 8F)at the location corresponding to the second media element and inaccordance with the user contact (e.g., 810 a) including atouch-and-hold input, the electronic device produces (920), using thetwo or more speakers, audio (e.g., 850 b) using a second audio file(different from the first audio file) that corresponds to the secondmedia element (e.g., 804 b) without exceeding the predetermined audioplayback duration. For example, the audio plays for a maximum of 5seconds (less than the total duration of the second audio file).

Further in response (918) to detecting the user contact (e.g., 810 a atFIG. 8F) at the location corresponding to the second media element andin accordance with the user contact (e.g., 810 a) including atouch-and-hold input, while (922) the user contact remains (e.g.,without a lift-off event) at the location corresponding to the secondmedia element (e.g., 804 b), and in accordance with the predeterminedaudio playback duration period not being exceeded, the electronic devicecontinues (924) to produce, using the two or more speakers, audio (e.g.,850 b) using the second audio file.

Further in response (918) to detecting the user contact (e.g., 810 a atFIG. 8F) at the location corresponding to the second media element andin accordance with the user contact (e.g., 810 a) including atouch-and-hold input, while the user contact remains (e.g., without alift-off event) at the location corresponding to the second mediaelement (e.g., 804 b), and in accordance with the predetermined audioplayback duration period being exceeded, the electronic device ceases(926) to produce, using the two or more speakers, audio (e.g., 850 b)using the second audio file (and, optionally, without beginning toproduce audio using a different audio file).

The electronic device detects (928), using the touch-sensitive surface,a lift-off of the user contact (e.g., 810 a at FIGS. 8G and 8H).

In response (930) to detecting the lift-off of the user contact, theelectronic device ceases (932) to produce, using the two or morespeakers, audio (e.g., 850 a and 850 b at FIG. 8I) using the first audiofile or the second audio file (and, optionally, ceasing to produce anyaudio using audio files that correspond to the plurality of mediaelements). Thus, playback of any song being previewed ceases.

In accordance with some embodiments, further in accordance with (906)the user contact including a touch-and-hold input (e.g., as determinedby the electronic device), producing audio using the first audio filewithout exceeding a predetermined audio playback duration includestransitioning the audio among a plurality of modes, including: a firstmode, a second mode that is different from the first mode (e.g., 850 aat FIG. 8D, 850 b at FIG. 8F), and a third mode that is different fromthe first mode and the second mode. Producing audio with varyingcharacteristics also provides the user with contextual feedback aboutthe placement of different content. Providing improved audio feedback tothe user enhances the operability of the device and makes theuser-device interface more efficient (e.g., by helping the user toprovide proper inputs) which, additionally, reduces power usage andimproves battery life of the device by enabling the user to use thedevice more quickly and efficiently.

In accordance with some embodiments, the first mode is configured suchthat audio produced using the first mode is perceived by the user asbeing produced from a first direction (e.g., 850 a at FIG. 8C, 850 b atFIG. 8E) (and optionally, location). In some examples, the firstdirection is a direction originating at a location that is to the leftof the user (e.g., not in front of the user). In some examples, theelectronic device modifies the source audio before producing the audiosuch that the audio is perceived by a user as being produced from adirection originating at a location that is to the left of the displayor user.

In accordance with some embodiments, the second mode is configured suchthat audio produced using the second mode is perceived by the user asbeing in the user's head (e.g., stereo, not a point source). Forexample, the second mode does not include applying any of HRTF,interaural time difference of audio, or cross cancellation.

In accordance with some embodiments, the third mode is configured suchthat audio produced using the third mode is perceived by the user asbeing produced from a third direction different from the first direction(e.g., 850 a at FIG. 8F, 850 b at FIG. 8H). In some examples, the thirddirection is a direction originating at a location that is to the rightof the user (e.g., not in front of the user). In some examples, theelectronic device modifies the source audio before producing the audiosuch that the audio is perceived by a user as being produced from adirection originating at a location that is to the right of the displayor user.

In accordance with some embodiments, the first mode includes a firstmodification of an interaural time difference of audio and the thirdmode includes a second modification of an interaural time difference ofaudio, different from the first modification. In some examples, thefirst mode includes a first degree modification of the interaural timedifference of audio and the third mode includes a second degreemodification, larger than the first degree, of the interaural timedifference of audio. In some examples, the first mode includes amodification of an interaural time difference of audio such that theaudio is perceived by a user as being produced from a directionoriginating at a location that is to the left of the display or user. Insome examples, the third mode includes a modification of an interauraltime difference of audio such that the audio is perceived by a user asbeing produced from a direction originating at a location that is to theright of the display or user. Modifying an interaural time difference ofaudio enables the user to perceive the audio as coming from a particulardirection. This directional information in the audio provides the userwith additional feedback about the placement of different content.Providing improved audio feedback to the user enhances the operabilityof the device and makes the user-device interface more efficient (e.g.,by helping the user to provide proper inputs) which, additionally,reduces power usage and improves battery life of the device by enablingthe user to use the device more quickly and efficiently.

In some embodiments, audio produced in the first mode (e.g., 850 a atFIG. 8C) is modified using one or more of an HRTF, an interaural timedifferent of audio, and cross cancellation. In some examples, audioproduced in the second mode (e.g., 850 a at FIG. 8D) is not modifiedusing any of an HRTF, an interaural time different of audio, or crosscancellation. In some examples, audio produced in the third mode (e.g.,850 a at FIG. 8F) is modified using one or more of an HRTF, aninteraural time different of audio, and cross cancellation.

In accordance with some embodiments, the second mode does not include amodification of an interaural time difference of audio. In someexamples, audio produced in the second mode is not modified using anHRTF. In some examples, audio produced in the second mode (e.g., 850 aat FIG. 8D) is not modified using any of an HRTF, an interaural timedifferent of audio, or cross cancellation.

In accordance with some embodiments, modification of the interaural timedifference of audio includes: combining a first channel audio (e.g., aright channel) of the audio and a second channel audio (e.g., a leftchannel) of the audio to form a combined channel audio, updating thesecond channel audio to include the combined channel audio at a firstdelay (e.g., Oms delay, less than a delay amount), updating the firstchannel audio to include the combined channel audio at a second delay(e.g., a 100 ms delay, more than the delay amount) different from thefirst delay. In some examples, modifying the interaural time differenceof audio includes introducing a time delay to a first channel audio(e.g., a right channel) without introducing a time delay to the secondchannel audio (e.g., a left channel) that is different from the firstaudio channel Modifying an interaural time difference of audio enablesthe user to perceive the audio as coming from a particular direction.This directional information in the audio provides the user withadditional feedback about the placement of different content. Providingimproved audio feedback to the user enhances the operability of thedevice and makes the user-device interface more efficient (e.g., byhelping the user to provide proper inputs) which, additionally, reducespower usage and improves battery life of the device by enabling the userto use the device more quickly and efficiently.

In accordance with some embodiments, further in response (906) todetecting the user contact (e.g., 810 a) at the location correspondingto the first media element (e.g., 804 a), changing a first visualcharacteristic (e.g., focus/blur level) of the displayed media elementsin the plurality of media elements (e.g., 804 b at FIG. 8C) other thanthe first media element (e.g., 804 a at FIG. 8C). In response todetecting the user contact (e.g., 810 a) at the location correspondingto the second media element (e.g., 804 ba), reverting the change of thefirst visual characteristic of the second media element (e.g., 804 b atFIG. 8E) and changing the first visual characteristic of the first mediaelement (e.g., 804 a at FIG. 8E). In some examples, the electronicdevice fades the media elements that are not activated. In someexamples, the electronic device adds a blur effect to the media elementsthat are not activated. In some examples, the electronic device changesa color of the media elements that are not activated. Visuallydifferentiating content being played from content not being playedprovides the user with feedback about the state of the device. Providingimproved visual feedback to the user enhances the operability of thedevice and makes the user-device interface more efficient (e.g., byhelping the user to provide proper inputs and reducing user mistakeswhen operating/interacting with the device) which, additionally, reducespower usage and improves battery life of the device by enabling the userto use the device more quickly and efficiently.

In accordance with some embodiments, in response to detecting the usercontact at the location corresponding to the first media element, theelectronic device changes a second visual characteristic of the firstmedia element without changing the second visual characteristic of thedisplayed media elements in the plurality of media elements other thanthe first media element. In response to detecting the user contact atthe location corresponding to the second media element, the electronicdevice reverts the change of the second visual characteristic of thefirst media element and changes the second visual characteristic of thesecond media element. In some examples, the electronic device highlightsthe media element that is activated. In some examples, the electronicdevice brightens the media element that is activated. In some examples,the electronic device changes a color of the media elements that isactivated. Visually differentiating content being played from contentnot being played provides the user with feedback about the state of thedevice. Providing improved visual feedback to the user enhances theoperability of the device and makes the user-device interface moreefficient (e.g., by helping the user to provide proper inputs andreducing user mistakes when operating/interacting with the device)which, additionally, reduces power usage and improves battery life ofthe device by enabling the user to use the device more quickly andefficiently.

In accordance with some embodiments, in response to detecting the usercontact at the location corresponding to the first media element and inaccordance with the user contact including a tap input (e.g., asdetermined by the electronic device), the electronic device producesaudio using the first audio file that corresponds to the first mediaelement without automatically ceasing to produce audio using the firstaudio after the predetermined audio playback duration and withoutautomatically ceasing to produce audio using the first audio file upondetecting lift-off of the user contact. For example, the audio plays forlonger than the preview time of 5 seconds.

In accordance with some embodiments, in accordance with the user contactincluding a tap input (e.g., as determined by the electronic device),producing audio using the first audio file includes producing audiousing the first audio file in the second mode without transitioning theaudio among the first mode and the third mode of the plurality of modes.

Note that details of the processes described above with respect tomethod 900 (e.g., FIGS. 9A-9C) are also applicable in an analogousmanner to the methods described below and above. For example, methods700, 1200, 1400, and 1500 optionally include one or more of thecharacteristics of the various methods described above with reference tomethod 900. For example, the same or similar techniques are used toplace audio in space. For another example, the same audio sources may beused in the various techniques. For yet another example, currentlyplaying audio in each of the various methods can be manipulated usingthe techniques described in other methods. For brevity, these detailsare not repeated below.

FIGS. 10A-10K illustrate exemplary techniques for discovering music, inaccordance with some embodiments. The techniques in these figures areused to illustrate the processes described below, including theprocesses in FIGS. 12A-12B.

FIGS. 10A-10K illustrate device 1000 (e.g., a mobile phone) with adisplay, a touch-sensitive surface, and left and right speakers (e.g.,headphones). Overhead view 1050 is a visual depiction of the spatialorganization of audio being produced by device 1000 and is illustratedthroughout FIGS. 10A-10K to provide the reader with a betterunderstanding of the techniques, in particular with respect to locationsfrom which the user 1056 perceives the sounds as coming from (e.g., as aresult of device 1000 placing audio in space). Overhead view 1050 is notpart of the user interface of device 1000. Similarly, visual elementsdisplayed outside of the display device are not part of the displayeduser interface, as represented by dotted outlines, but are illustratedto provide the reader with a better understanding of the techniques. Insome examples, the techniques described below enable users to moreeasily and efficiently discover new songs from a song repository.

At FIG. 10A, device 1000 displays a music player 1002 that includes anaffordance 1002 a for discovering new audio content. At FIG. 10A, device1000 is not producing any audio, as illustrated by the lack audioelements in overhead view 1050 of FIG. 10A. While device 1000 is notproducing any audio, device 1000 detects tap input 1010 a on affordance1002 a. In response to detecting tap input 1010 a on affordance 1002 a,device 1000 enters a discovery mode.

At FIG. 10B, device 1000 replaces display of affordance 1002 a withdisplay of album art 1004 a. Album art 1004 a corresponds to a firstsong (e.g., the album art is of the album that the song belongs to) andalbum art 1004 b corresponds to a second song different from the firstsong. Audio element 1054 a corresponds to the first song and audioelement 1054 b corresponds to the second song.

At FIG. 10B, device 1000 produces audio of the first song and the secondsong, using the left and right speakers, by placing audio of the firstsong and the second song in space (e.g., device 1000 applies aninteraural time difference, an HRTF, and/or cross cancellation) alongpath 1050 a. For example, path 1050 a is a fixed path that is curved,along which the device places the audio of the various songs while inthe discovery mode. Device 100 produces audio of the first song and thesecond song and updates the placement of the audio such that the userperceives the audio of the song as drifting in front of the user fromleft to right along path 1050 a, as illustrated by audio element 1054 aand audio element 1054 b in overhead view 1050 of FIGS. 10B-10G. In someexamples, the direction at which the songs move along the path 1050 a isnot based on input provided by the user (e.g., not based on tap input1010 a).

At FIG. 10C, as the first song and the second song progress along path1050 a, device 1000 begins producing audio of a third song, using theleft and right speakers, by placing and transitioning the audio in space(e.g., device 1000 applies an interaural time difference, an HRTF,and/or cross cancellation), such that the user perceives the audio asdrifting in front of the user from left to right along path 1050 a, asillustrated by audio element 1054 c in overhead view 1050 of FIGS.10C-10G.

At FIGS. 10D-10F, device 1000 begins producing additional audio of songs(while continuing to produce audio of the first song and the secondsong), using the left and right speakers, by placing and transitioningthe audio of the respective songs in space (e.g., device 1000 applies aninteraural time difference, an HRTF, and/or cross cancellation) suchthat the user perceives the audio as drifting in front of the user fromleft to right along path 1050 a, as illustrated by audio elements 1054a-1054 e in overhead view 1050 of FIGS. 10C-10G. In some examples,device 1000 places the songs at equal distances apart (e.g., perceivedfrom the user as being 2 meters to 3 meters apart) along path 1050 a. Insome examples, the distance between songs changes (e.g., increases) asthe songs get closer to a point on path 1050 a (e.g., a point in frontof the user) and the distance between songs changes (e.g., decreases) asthe songs get further from the point on path 1050 a. In some examples,each song moves at the same speed along path 1050 a. In some examples,device 1000 ceases to produce songs that reach a certain point alongpath 1050 a (e.g., they get more than a threshold distance away from theuser). In some examples, device 1000 attenuates songs based on theirposition along path 1050 a (e.g., the further from the user the moreattenuated the song).

As illustrated in FIGS. 10B-10I, album art 1004 a-1004 e correspond tothe various songs. Device 1000 displays respective album art for songsplaced in front of the user. For example, device 1000 displays album artthat corresponds to songs that are placed along a certain subset of path1050 a. The displayed album art moves in the same direction on thedisplay as the various audio moves along path 1050 a (e.g., left toright).

The first song (visualized as audio element 1054 a in overhead view1050) corresponds to album art 1004 a (e.g., the album art is of thealbum that the song belongs to). The second song (visualized as audioelement 1054 b in overhead view 1050) corresponds to album art 1004 b.The third song (visualized as audio element 1054 c in overhead view1050) corresponds to album art 1004 c. The fourth song (visualized asaudio element 1054 d in overhead view 1050) corresponds to album art1004 d. The fifth song (visualized as audio element 1054 e in overheadview 1050) corresponds to album art 1004 e.

At FIGS. 10G-10H, device 1000 detects a left-swipe input 1010 b. Inresponse to detecting the left-swipe input 1010 b, device 1000 changesthe direction at which the album art moves on the display to correspondto the left-swipe input 1010 b and changes the direction along which thevarious audio moves along path 1050 a to correspond to the left-swipeinput 1010 b. At FIG. 10G, when the user places their finger on thetouch-sensitive surface, the album art 1004 d and 1004 c stops moving onthe display and the audio corresponding to audio elements 1054 a-1054 estop moving along path 1050 a. At FIG. 10H, as device 1000 detects theleft-swipe input 1010 b from the right to the left, device 100 updatesthe display such that album art 1004 d and 1004 c moving on the displayfrom the right to the left and the audio corresponding to audio elements1054 a-1054 e move along path 1050 a from the right to the left. In someexamples, the speed at which the album art 1004 a-1004 e move across thedisplay and the speed at which audio corresponding to audio elements1054 a-1054 e move along path 1050 a are based on one or morecharacteristics (e.g., length, speed, characteristic intensity) ofleft-swipe input 1010 b. In some examples, a faster swipe results infaster movement of the album art on the display and the audio along path1050 a. In some examples, a longer swipe results in faster movement ofthe album art on the display and the audio along path 1050 a.

At FIG. 10I, after device 1000 stops detecting left-swipe input 1010 b,device 1000 continues to display album art 1004 a-1004 e moving acrossthe display from the left to the right and audio corresponding to audioelements 1054 a-1054 e continue to move along path 1050 a from the leftto the right. Thus, the left-swipe input 1010 b has changed thedirection at which the user perceives the audio move along path 1050 aand has changed the direction at which device 1000 moves thecorresponding album art on the display.

At FIG. 10J, device 1000 detects tap input 1010 c on album art 1004 b.In response to detecting tap input 1010 c on album art 1004 b, asillustrated in FIGS. 10J-10K, device 1000 transitions to producing,using the left and right speakers, audio of the second song thatcorresponds to album art 1004 b without placing the audio (e.g., device1000 does not apply any of an interaural time difference, an HRTF, orcross cancellation). For example, as a result of not placing the audioin space, a user of device 1000 wearing headphones perceives the audioof the second song as being in the head of the user, as illustrated byaudio element 1054 b in overhead view 1050 of FIG. 10K. Further inresponse to detecting tap input 1010 c on album art 1004 b, asillustrated in FIGS. 10J-10K, device 1000 moves the audio correspondingto audio elements 1054 c and 1054 a in opposite directions away from theuser before ceasing to produce the audio corresponding to audio elements1054 c and 1054 a. Thus, the user perceives the audio of the unselectedsongs as floating away.

In some examples, device 1000 includes a digital assistant that producesaudio feedback, such as returning the results of a query by speaking theresults. In some examples, device 1000 produces audio for the digitalassistant by placing the audio for the digital assistant at a locationin space (e.g., over the right shoulder of the user) such that the userperceives the digital assistant as remaining stationary in space evenwhen other audio moves in space. In some examples, device 1000emphasizes the audio for the digital assistant by ducking one or more(or all) other audio.

FIGS. 11A-11G illustrate exemplary techniques for discovering music, inaccordance with some embodiments. FIGS. 11A-11G illustrate exemplaryuser interfaces for display by a device (e.g., a laptop) with a display,a touch-sensitive surface (e.g., 1100), and left and right speakers(e.g., headphones). Touch-sensitive surface 1100 of the device isillustrated to provide the reader with a better understanding of thetechniques described, in particular with respect to exemplary userinputs. Touch-sensitive surface 1100 is not part of the displayed userinterface of the device. Overhead view 1150, which is illustratedthroughout FIGS. 11A-11G, is displayed by the device. Overhead view 1150is also a visual depiction of the spatial organization of audio beingproduced by the device and provides the reader with a betterunderstanding of the techniques, in particular with respect to locationsfrom which the user 1106 perceives the sounds as coming from (e.g., as aresult of the device placing audio in space). The arrows of audioelements 1150 a-1150 g indicate the direction and speed with which theaudio elements 1150 a-1150 g are moving (including visual display and asperceived by the user through the speakers) and provide the reader witha better understanding of the techniques. In some examples, thedisplayed user interface does not include the arrows of audio elements1150 a-1150 g. Similarly, visual elements displayed outside of thedisplay of the device are not part of the displayed user interface, butare illustrated to provide the reader with a better understanding of thetechniques. In some examples, the techniques described below enableusers to more easily and efficiently discover new songs from a songrepository.

FIGS. 11A-11D illustrate the device displaying representation 1106 ofthe user in space. The device also illustrated audio elements 1150a-1150 f, which correspond to songs 1-6, respectively, in the samespace. The device concurrently produces, using left and right speakers)audio for each of songs 1-6 by placing and transitioning the individualsongs in space (e.g., the device applies an interaural time difference,an HRTF, and/or cross cancellation) such that the user perceives theaudio of the songs drifting past the user, as illustrated by audioelements 1150 a-1150 f in overhead view 1150 of FIGS. 11A-11D. In someexamples, the audio elements are displayed such that they areequidistant from each other. In some examples, the audio produced isplaced such that the user perceives the song sources as beingequidistant from each other. In FIG. 6A, for example, the user perceivessong 1 (corresponding to audio element 1150 a) and song 2 (correspondingto audio element 1150 b) as being substantially in front of the user,song 6 (corresponding to audio element 11500 as being substantially tothe right of the user, and song 4 (corresponding to audio element 1150d) as being substantially to the left of the user. As the devicecontinues producing the songs, the user perceives the audio sourcespassing by. For example, in FIG. 11D, the user perceives song 6 as beingsubstantially behind the user. This allows the user to concurrently tolisten various songs.

At FIGS. 11D-11E, the device receives, at touch-sensitive surface 1100,swipe input 1110. In response to receiving swipe input 1110, asillustrated in FIGS. 11E-11F, the device updates, on the display, thedirection and/or speed of displayed visual elements 1150 a-1150 h (e.g.,in accordance with a direction and/or speed of swipe input 1110).Further in response to receiving swipe input 1110, the devicetransitions the audio produced for individual songs in space (e.g., thedevice applies an interaural time difference, an HRTF, and/or crosscancellation) such that the user perceives the audio of the songs asdrifting past the user with an updated direction and/or speed (e.g., inaccordance with the direction and/or speed of swipe input 1110).

In some examples, the device includes a digital assistant that producesaudio feedback, such as returning the results of a query by speaking theresults. In some examples, device produces audio for the digitalassistant by placing the audio for the digital assistant at a locationin space (e.g., over the right shoulder of the user) such that the userperceives the digital assistant as remaining stationary in space evenwhen other audio moves in space. In some examples, the device emphasizesthe audio for the digital assistant by ducking one or more (or all)other audio.

In some examples, the device detects a tap input on (e.g., at a locationon the touch-sensitive surface corresponding to) a displayed audioelement. In response to detecting the tap input on the audio element,the device transitions to producing, using the left and right speakers,audio of the respective song that corresponds to selected audio elementwithout placing the audio in space (e.g., device 1000 does not apply anyof an interaural time difference, an HRTF, or cross cancellation). Forexample, as a result of not placing the audio in space, a user wearingheadphones perceives the audio of the selected song as being in the headof the user. Further in response to detecting the tap input on thedisplayed audio element, the device ceases to produce audio of theremaining audio elements. Thus, the user is enabled to select anindividual song to listen to.

FIGS. 12A-12B is a flow diagram illustrating a method for discoveringmusic using an electronic device in accordance with some embodiments.Method 1200 is performed at a device (e.g., 100, 300, 500, 1000) with adisplay and a touch-sensitive surface. The electronic device is operablyconnected with two or more speakers (e.g., left and right speakers, leftand right headphones, left and right earphones, left and right earbuds).Some operations in method 1200 are, optionally, combined, the orders ofsome operations are, optionally, changed, and some operations are,optionally, omitted.

As described below, method 1200 provides an intuitive way fordiscovering music. The method reduces the cognitive burden on a user fordiscovering music, thereby creating a more efficient human-machineinterface. For battery-operated computing devices, enabling a user todiscover music faster and more efficiently conserves power and increasesthe time between battery charges.

The electronic device detects (1202) a first user input (e.g., 1010 a)for activating a discovery mode (e.g., by tapping a “discover”affordance, providing voice input to a digital assistant, such as“Sample some songs”).

In response (1204) to detecting the first user input (e.g., 1010 a) foractivating the discovery mode, the electronic device concurrentlyproduces (1204), using the two or more speakers, audio (e.g., 1054 a,1054 b, 1054 c) using: a first audio source (e.g., audio file, musicfile, media file) in a first mode (1206), a second audio source (e.g.,audio file, music file, media file) in a second mode (1210), and a thirdaudio source (e.g., audio file, music file, media file) in a third mode(1214)

The first mode (1206) is configured such that audio produced using thefirst mode is perceived by the user as being produced from a first pointin space that moves over time in a first direction (e.g., a left toright direction) along a predefined path (e.g., 1050 a) at a firstspeed.

In accordance with some embodiments, the first audio source (e.g., audiofile, music file, media file) corresponds (1208) to a first visualelement (e.g., 1004 a, audio of the video in the playback window, audioof the song from the album corresponding to the album art, audiogenerated by, or received from, the first application).

The second mode (1210) is configured such that audio produced using thesecond mode is perceived by the user as being produced from a secondpoint in space that moves over time in the first direction (e.g., a leftto right direction) along the predefined path (e.g., 1050 a) at a secondspeed.

In accordance with some embodiments, the second audio source (e.g.,audio file, music file, media file) corresponds (1212) to a secondvisual element (e.g., 1004 b, audio of the video in the playback window,audio of the song from the album corresponding to the album art, audiogenerated by, or received from, the first application).

The third mode (1214) is configured such that audio produced using thethird mode is perceived by the user as being produced from a third pointin space that moves over time in the first direction (e.g., a left toright direction) along the predefined path (e.g., 1050 a) at a thirdspeed.

In accordance with some embodiments, the third audio source (e.g., audiofile, music file, media file) corresponds (1216) to a third visualelement (e.g., 1004 c, audio of the video in the playback window, audioof the song from the album corresponding to the album art, audiogenerated by, or received from, the first application).

The first point (e.g., location of 1054 a at FIG. 10C), the second point(e.g., location of 1054 b at FIG. 10C), and the third point (e.g.,location of 1054 c at FIG. 10C) are different (1218) points in space(e.g., different points in space as perceived by the user). Producingaudio with varying characteristics also provides the user withcontextual feedback about the placement of different content and enablesusers to quickly and easily recognize what inputs are required to accessthe content (e.g., to cause display of the content). For example, theuser can recognize that a particular audio can be access with aparticular input based on where in space the user perceives the audio asfrom coming from. Providing improved audio feedback to the user enhancesthe operability of the device and makes the user-device interface moreefficient (e.g., by helping the user to provide proper inputs) which,additionally, reduces power usage and improves battery life of thedevice by enabling the user to use the device more quickly andefficiently.

In accordance with some embodiments, concurrently with producing audiousing the first audio source, second audio source, and third audiosource, the electronic device displays (1220), on the display,concurrent movement of two or more of the first visual element (e.g.,1004 a), the second visual element (e.g., 1004 b), and the third visualelement (e.g., 1004 c) at a fourth speed. In some examples, the devicedisplays concurrent movement of all of the first visual element (e.g.,1004 a), the second visual element (e.g., 1004 b), and the third visualelement (e.g., 1004 c) at a fourth speed.

In accordance with some embodiments, the movement of the two or more ofthe first visual element (e.g., 1004 a), the second visual element(e.g., 1004 b), and the third visual element (e.g., 1004 c) is in thefirst direction (e.g., a left to right direction).

In accordance with some embodiments, the predefined path (e.g., 1050 a)varies along a first dimension (e.g., x dimension, left/rightdimension). The predefined path varies along a second dimension (e.g., zdimension, near/far dimension) different from the first dimension. Thepredefined path does not vary along a third dimension (e.g., ydimension, up/down dimension, height) different from the first dimensionand the second dimension. Thus, in some examples, the devices producesaudio along a path such that the user perceives the audio moving fromleft-to-right and/or right-to-left and from further-to-nearer ornearer-to-further, but does not perceive the audio as moving up-to-downor down-to-up.

In accordance with some embodiments, concurrently producing (1204),using the two or more speakers, audio further includes using a fourthaudio source (e.g., audio file, music file, media file) in a fourthmode. The fourth mode is configured such that audio (e.g., 1054 d)produced using the fourth mode is perceived by the user as beingproduced from a fourth point in space (e.g., location of 1054 a) thatmoves over time in the first direction (e.g., a left to right direction)along the predefined path (e.g., 1050 a), the fourth point in spacebeing further from the user than the first point, the second point, andthe third point. In some examples, visual elements of audio that areperceived as being off in the distance (e.g., further than apredetermined distance) are not displayed on the display (e.g., 1004 ain FIG. 10E is not displayed on the display). While displaying, on thedisplay, the concurrent movement of the two or more of the first visualelement (e.g., 1004 a), the second visual element (e.g., 1004 b), andthe third visual element (e.g., 1004 c), the electronic device forgoesdisplaying, on the display, a fourth visual element (e.g., 1004 d) thatcorresponds to the fourth audio source.

In accordance with some embodiments, the first speed, the second speed,and the third speed are the same speed. In accordance with someembodiments, the first speed, the second speed, and the third speed aredifferent speeds.

In accordance with some embodiments, while concurrently producing, usingthe two or more speakers, the audio (e.g., as illustrated in 1050 ofFIG. 10F), the electronic device detects a second user input (e.g., 1010b) in a second direction (e.g., a right to left direction) that isdifferent from the first direction (e.g., a left to right direction). Inresponse to detecting the second user input (e.g., 1010 b) in the seconddirection, the electronic device updates production of the audio of thefirst audio source, the second audio source, and the third audio sourceusing modes configured such that the audio sources are perceived by theuser as moving over time in the second direction (e.g., a right to leftdirection, as illustrated in 1050 of FIG. 10H) along the predefined path(e.g., 1050 a). Further in response to detecting the second user input(e.g., 1010 b) in the second direction, the electronic device updatesdisplay, on the display, of the movement of one or more of (e.g., two ormore of, all of) the first visual element (e.g., 1004 a), the secondvisual element (e.g., 1004 a), and the third visual element (e.g., 1004a) such that the movement is in the second direction (e.g., a right toleft direction, as illustrated in FIGS. 10H-10I).

In accordance with some embodiments, while concurrently producing, usingthe two or more speakers, the audio, the electronic device detects athird user input (e.g., in the first direction, a left to rightdirection). In response to detecting the third user input, theelectronic device updates production of the audio of the first audiosource, the second audio source, and the third audio source using modesconfigured such that the audio sources are perceived by the user asmoving over time in the first direction (e.g., a right to leftdirection) along the predefined path at a fifth speed that is fasterthan the first speed. Further in response to detecting the third userinput, the electronic device updates display, on the display, of theconcurrent movement of the first visual element, the second visualelement, and the third visual element such that the movement is in thefirst direction (e.g., a left to right direction) at a sixth speed thatis faster than the fourth speed.

In accordance with some embodiments, the electronic device detects aselection input (e.g., 1010 c, a tap input, a tap-and-hold input) at alocation corresponding to the second visual element (e.g., 1004 b). Inresponse to detecting the selection input (e.g., 1010 c), the electronicdevice produces, using the two or more speakers, audio of the secondaudio file in a fifth mode (and not in the second mode). The audioproduced using the fifth mode is not perceived by the user as beingproduced from a point in space that moves over time.

In accordance with some embodiments, the fifth mode does not include amodification of an interaural time difference of audio. In someexamples, audio produced in the fifth mode (e.g., 1054 b at FIG. 10K) isnot modified using any of an HRTF, an interaural time different ofaudio, or cross cancellation.

In accordance with some embodiments, the first mode, second mode, andthe third mode include modification of an interaural time difference ofaudio. In some examples, audio produced in the first mode is modifiedusing one or more of an HRTF, an interaural time different of audio, andcross cancellation. In some examples, audio produced in the second modeis modified using one or more of an HRTF, an interaural time differentof audio, and cross cancellation. In some examples, audio produced inthe third mode is modified using one or more of an HRTF, an interauraltime different of audio, and cross cancellation. Modifying an interauraltime difference of audio enables the user to perceive the audio ascoming from a particular direction. This directional information in theaudio provides the user with additional feedback about the placement ofdifferent content. Providing improved audio feedback to the userenhances the operability of the device and makes the user-deviceinterface more efficient (e.g., by helping the user to provide properinputs) which, additionally, reduces power usage and improves batterylife of the device by enabling the user to use the device more quicklyand efficiently.

In accordance with some embodiments, modification of the interaural timedifference of audio includes: combining a first channel audio (e.g., aright channel) of the audio and a second channel audio (e.g., a leftchannel) of the audio to form a combined channel audio, updating thesecond channel audio to include the combined channel audio at a firstdelay (e.g., Oms delay, less than a delay amount), and updating thefirst channel audio to include the combined channel audio at a seconddelay (e.g., a 100 ms delay, more than the delay amount) different fromthe first delay. In some examples, modifying the interaural timedifference of audio includes introducing a time delay to a first channelaudio (e.g., a right channel) without introducing a time delay to thesecond channel audio (e.g., a left channel) that is different from thefirst audio channel.

Note that details of the processes described above with respect tomethod 1200 (e.g., FIGS. 12A-12B) are also applicable in an analogousmanner to the methods described below and above. For example, methods700, 900, 1400, and 1500 optionally include one or more of thecharacteristics of the various methods described above with reference tomethod 1200. For example, the same or similar techniques are used toplace audio in space. For another example, the same audio sources may beused in the various techniques. For yet another example, currentlyplaying audio in each of the various methods can be manipulated usingthe techniques described in other methods. For brevity, these detailsare not repeated below.

FIGS. 13A-13F illustrate exemplary techniques for managing headphonetransparency, in accordance with some embodiments. The techniques inthese figures are used to illustrate the processes described below,including the processes in FIGS. 14A-14B.

FIGS. 13G-13M illustrate exemplary techniques for manipulating multipleaudio streams of an audio source, in accordance with some embodiments.The techniques in these figures are used to illustrate the processesdescribed below, including the processes in FIG. 15 .

FIGS. 13A-13M illustrate device 1300 (e.g., a mobile phone) with adisplay and a touch-sensitive surface that is connected to left andright speakers (e.g., headphones 1358). In some examples, the left andright speakers are operable to individually operate at a noisecancellation level (e.g., noises from outside of the headphones aresuppressed, so the user hears less of those noises—thus, a low state ofnoise transparency) and a full transparency level (e.g., noises fromoutside of the headphones are fully passed through to the user, orpassed through as much as the headphones are able, so the user can hearthose noises—thus, a high state of noise transparency). In FIGS.13A-13C, device 1300 is operating left speaker 1358 a and right speaker1358 b at the noise cancellation level, as illustrated by the speakersbeing filled. However, for example, device 1300 can operate left speaker1358 a at the noise cancellation level while operating right speaker1358 b at the full transparency level.

Overhead view 1350 is a visual depiction of the spatial organization ofaudio being produced by device 1300 and is illustrated throughout FIGS.13A-13M to provide the reader with a better understanding of thetechniques, in particular with respect to locations from which the user1356 perceives sounds as coming from (e.g., as a result of device 1300placing audio in space). Overhead view 1350 is not part of the userinterface of device 1300. In some examples, the techniques describedbelow enable users to more easily and efficiently listen to audiosources not produced a device they are currently listening to. Forinstance, the techniques enable a user to more clearly hear someonespeaking to the user while the user is listening to music usingheadphones. In some examples, the techniques described below enableusers to easily manipulate various streams of audio.

At FIG. 13A, device 1300 displays music player 1304, which includesalbum art 1304 a and, optionally, axes 1304 b. The album art correspondsto a song being played by device 1300. In some examples, the songincludes a plurality of audio streams. In this examples, the songincludes five audio steams, where each audio stream corresponds to aparticular instrument.

At FIG. 13A, device 1300 produces, using the left 1358 a and right 1358b speakers, audio for the song (including all five audio streams)without placing the audio in space (e.g., device 1300 does not apply anyof an interaural time difference, an HRTF, or cross cancellation). Forexample, this results in the user perceiving the audio as being in thehead of user 1356, as illustrated by audio element 1354 in overhead view850 of FIG. 8F-8G. Audio element 1354 corresponds to the song, includingthe five audio streams. Device 1300 is configured such that user inputsreceived at affordances 1304 c control the music, such as by pausing,playing, fast forwarding, and rewinding the music.

In some examples, user 1356 sees that a person to the right of them isspeaking and the user provides drag input 1310 a. At FIGS. 13B-13D,device 1300 detects drag input 1310 a, which displaces album art 1304 a.For example, device 1300 updates display of the location of album art1304 a such that it corresponds to the movement of drag input 1310 a.

At FIGS. 13B and 13C, the displacement of album art 1304 a does notexceed a predetermined distance and device 1300 continues producing,using left 1358 a and right 1358 b speakers, audio for the song(including all five audio streams) without placing the audio in space(e.g., device 1300 does not apply any of an interaural time difference,an HRTF, or cross cancellation) and while maintaining operation of left1358 a and right 1358 b speakers at the noise cancellation level.

At FIG. 13D, device 1300 determines that displacement of album art 1304a exceeds the predetermined distance (e.g., the user has moved album art1304 a far enough). In response to the determination that thedisplacement of album art 1304 a exceeds the predetermined distance,device 1300 transitions to producing, using left 1358 a and right 1358 bspeakers, audio for the song (including all five audio streams) byplacing the audio in space (e.g., device 1300 applies an interaural timedifference, an HRTF, and/or cross cancellation) such that the userperceives the audio as being at a location in space that is away (e.g.,forward and to the left) from the person to the right of the user, asillustrated in overhead view 1350 of FIG. 13D. In some examples, theaudio is moved to a location in space based on the direction and/ordistance of drag input 1310 a. Further in response to the determinationthat the displacement of album art 1304 a exceeds the predetermineddistance, device 1300 maintains operation of left speaker 1358 a at thenoise cancellation level and transitions operation of right speaker 1358b to the full transparency level, as illustrated in overhead view 1350of FIG. 13D by left speaker 1358 a being filled and right speaker 1358 bnot being filled.

While device 1300 maintains placement of the audio in space (e.g.,device 1300 applies an interaural time difference, an HRTF, and/or crosscancellation), operates left speaker 1358 a at the noise cancellationlevel, and operates right speaker 1358 b at the full transparency level,at FIG. 13E device 1300 detects lift-off of drag input 1310 a.

In response to detecting lift-off of drag input 1310 a, as illustratedin FIG. 13F, device 1300 returns display of album art 1304 a to theoriginal pre-drag position and transitions to producing, using left 1358a and right 1358 b speakers, audio for the song (including all fiveaudio streams) without placing the audio in space (e.g., device 1300does not apply any of an interaural time difference, an HRTF, and/orcross cancellation) such that the user perceives the audio as being inthe head of the user. Further in response to detecting lift-off of draginput 1310 a, device 1300 maintains operation of left speaker 1358 a atthe noise cancellation level and transitions operation of right speaker1358 b to the noise cancellation level, as illustrated in overhead view1350 of FIG. 13D by left speaker 1358 a and right speaker 1358 b beingfilled.

In some examples, in response to detecting lift-off of drag input 1310a, device 1300 maintains the placement of the audio in space andmaintains operation of right speaker 1358 b at the full transparencylevel.

At FIG. 13G, device 1300 continues to produce, using the left 1358 a andright 1358 b speakers, audio for the song (including all five audiostreams) without placing the audio in space (e.g., device 1300 does notapply any of an interaural time difference, an HRTF, or crosscancellation). At FIG. 13G, device 1300 detects input 1310 b.

In some examples, device 1300 determines whether a characteristicintensity of input 1310 b exceeds an intensity threshold. In response todevice 1300 determining that the characteristic intensity of input 1310b does not exceed an intensity threshold, device 1300 continues toproduce, using the left 1358 a and right 1358 b speakers, audio for thesong (including all five audio streams) without placing the audio inspace.

In response to device 1300 determining that the characteristic intensityof input 1310 b does exceed an intensity threshold, device 1300transitions to producing, using the left 1358 a and right 1358 bspeakers, audio for the various audio streams for the song (includingall five audio streams) by placing the various audio in space such thatthe user perceives the various audio streams as leaving the user's headin different directions, as illustrated by audio element 1354 splittingup into audio elements 1354 a-1354 e in FIGS. 13G-131 . Further inresponse to device 1300 determining that the characteristic intensity ofinput 1310 b does exceed an intensity threshold, device 1300 updatesdisplay of music player 1304 to show an animation of stream affordances1306 a-1306 e being displayed and spreading apart, as illustrated inFIGS. 13H-131 . For example, each of stream affordances 1306 a-1306 ecorrespond to respective audio stream of the song. For example, streamaffordance 1306 a corresponds to a first audio stream that includes asinger (but does not include guitar, keyboard, drums, etc). Similarly,audio element 1354 a corresponds to the first audio stream. For anotherexample, stream affordance 1306 d corresponds to a second audio streamthat includes a guitar (but does not include a singer, keyboard, drums,etc). Similarly, audio element 1354 d corresponds to the second audiostream.

As illustrated in FIGS. 13H-131 , device 1300 displays streamaffordances 1306 a-1306 e at locations on the display (e.g., relative toeach other, relative to a point on the display) that corresponds tolocations in space at which device 1300 has placed corresponding audiostreams.

At FIG. 13J-13K, device 1300 detects drag gesture 1310 c on streamaffordance 1306 d. In response to detecting drag gesture 1310 c, device1300 transitions to producing, using the left 1358 a and right 1358 bspeakers, audio for the second audio stream (corresponding to audioelement 1354 e) without placing the audio in space such that the userperceives the audio for the second audio stream as being in the usershead and continues producing the other various audio streams (e.g.,corresponding to audio elements 1354 a-1354 d) for the song at variousplaces in space, as illustrated by audio elements 1354 a-1354 e in FIG.13K. Thus, the device moves individual audio streams of the song intoand out of the user's head and to different positions in space based ondetecting drag inputs on corresponding stream affordance 1306 a-1306 d.In some examples, the device places the various audio streams atlocations in space based on the detected drag inputs (e.g., direction ofmovement, placement of liftoff).

At FIG. 13L, device 1300 detects tap input 1310 d on stream affordance1306 a. In response to detecting tap input 1310 d on stream affordance1306 a, device 1300 ceases to produce audio for the second audio stream,thus disabling the audio stream. Further in response to detecting tapinput 1310 d on stream affordance 1306 a, device 1300 updates one ormore visual characteristics (e.g., shading, size, movement) of streamaffordance 1306 a to indicate that the corresponding audio stream isdisabled. In some examples, device 1300 receives input that moves thedisabled audio stream to a new location in space (e.g., drag gesture onstream affordance 1306 a), without producing the disabled audio stream.In response to detecting an additional tap input on a stream affordancethat corresponds to the disabled audio stream, device 1300 enables theaudio stream and begins producing audio for the enabled audio stream atthe new location in space.

In some examples, device 1300 includes a digital assistant that producesaudio feedback, such as returning the results of a query by speaking theresults. In some examples, device 1300 produces audio for the digitalassistant by placing the audio for the digital assistant at a locationin space (e.g., over the right shoulder of the user) such that the userperceives the digital assistant as remaining stationary in space evenwhen other audio moves in space. In some examples, device 1300emphasizes the audio for the digital assistant by ducking one or more(or all) other audio.

FIGS. 14A-14B is a flow diagram illustrating a method for managingheadphone transparency using an electronic device in accordance withsome embodiments. Method 1400 is performed at a device (e.g., 100, 300,500, 1300) with a display and a touch-sensitive surface. The electronicdevice is operably connected with two or more speakers (e.g., left andright speakers, left and right headphones, left and right earphones,left and right earbuds). Some operations in method 1400 are, optionally,combined, the orders of some operations are, optionally, changed, andsome operations are, optionally, omitted.

As described below, method 1400 provides an intuitive way for managingheadphone transparency. The method reduces the cognitive burden on auser for managing headphone transparency, thereby creating a moreefficient human-machine interface. For battery-operated computingdevices, enabling a user to manage headphone transparency faster andmore efficiently conserves power and increases the time between batterycharges.

The electronic device displays (1402), at a first location on thedisplay, a user-movable affordance (e.g., 1304 a, album art).

While (1404) the user-movable affordance (e.g., 1304 a) is displayed atthe first location (e.g., 1304 a as illustrated in FIG. 13A), theelectronic device operates (1408) the electronic device in a first stateof ambient sound transparency (e.g., a state where transparency isdisable for both the first speaker and the second speaker of the two ormore speakers, a state where external noises are suppressed for thefirst speaker and for the second speaker of the two or more speakers,1358 a and 1358 b as illustrated in FIG. 13A).

While (1404) the user-movable affordance (e.g., 1304 a) is displayed atthe first location (e.g., 1304 a as illustrated in FIG. 13A), theelectronic device produces (1410), using the two or more speakers, audio(e.g., 1354) using an audio source (e.g., audio file, music file, mediafile) in a first mode (e.g., 1354 of FIG. 13A, a stereo mode, withoutapplying any of an HRTF, cross cancellation, or interaural timedifference).

While (1404) the user-movable affordance (e.g., 1304 a) is displayed atthe first location (e.g., 1304 a as illustrated in FIG. 13A), theelectronic device detects (1412), using the touch-sensitive surface,user input (e.g., 1310 a, a drag gesture).

A set of one or more conditions includes (1416) a first condition thatis met when the user input (e.g., 1310 a) is a touch-and-drag operationon the user-movable affordance (e.g., 1304 a). In accordance with someembodiments, the set of one or more conditions further includes (1418) asecond condition that is met when the user input causes displacement ofthe user-movable affordance from the first location by at least apredetermined amount. For example, small movement of the moveableaffordance (e.g., 1304 a) does not cause a change—the moveableaffordance (e.g., 1304 a) must be moved a minimum distance between themode is changed from the first mode to the second mode and before thestate is changed from the first state to the second state. This helps toavoid inadvertent mode and state changes.

In response (1414) to detecting the user input (e.g., 1310 a), and inaccordance with (1416) the set of one or more conditions being met, theelectronic device operates (1420) the electronic device in a secondstate of ambient sound transparency (e.g., a state where transparency isenabled for the first speaker and transparency is disabled for thesecond speaker of the two or more speakers, a state where externalnoises are suppressed for the first speaker and external noises are notsuppressed for the second speaker of the two or more speakers, 1358 aand 1358 b as illustrated in FIG. 13D) different from the first state ofambient sound transparency. Changing the state of ambient soundtransparency enables the user to hear sounds better from the user'senvironment, and specifically sound from a particular direction in theenvironment.

Further in response (1414) to detecting the user input (e.g., 1310 a),and in accordance with (1416) the set of one or more conditions beingmet, the electronic device transitions (1422) production of audio (e.g.,1354 as illustrated in FIG. 13D) using the audio source from the firstmode to a second mode (e.g., mono mode, applying one or more of an HRTF,cross cancellation, and interaural time difference) different from thefirst mode. Changing the mode at which audio is produced enables theuser to hear sounds better from the user's environment, and specificallysound from a particular direction in the environment (e.g., theparticular direction being away from the direction to which theproduction of audio has been moved in space).

Further in response (1414) to detecting the user input (e.g., 1310 a),and in accordance with (1424) the set of one or more conditions notbeing met, the electronic device maintains (1426) the electronic devicein the first state of ambient sound transparency (e.g., a state wheretransparency is disable for both the first speaker and the secondspeaker).

Further in response (1414) to detecting the user input (e.g., 1310 a),and in accordance with (1424) the set of one or more conditions notbeing met, the electronic device maintains producing audio (e.g., 1354as illustrated in FIG. 13C) using the audio source in the first mode.

In some examples, the speakers (e.g., headphones) are operable tooperate at a full noise cancellation level (e.g., noises from outside ofthe headphones are suppressed, suppressed as much as the headphones areable, so the user cannot hear those noises—thus, a low state of noisetransparency) and a full transparency level (e.g., noises from outsideof the headphones are fully passed through to the user, or passedthrough as much as the headphones are able, so the user can hear thosenoises—thus, a high state of noise transparency).

Further in response (1414) to detecting the user input (e.g., 1310 a),the electronic device updates (1430) display, on the display, of theuser-movable affordance (e.g., 1304 a) from the first location (e.g.,location of 1304 a in FIG. 13A) on the display to a second location(e.g., location of 1304 a in FIG. 13D) on the display in accordance withmovement, on the touch-sensitive surface, of the user input (e.g., 1310a). In some examples, the display location of the user-movableaffordance (e.g., 1304 a) is based on the user input, such as byupdating display of the user-movable affordance (e.g., 1304 a) tocorrespond to the location of a contact of the user input. Thus, thefarther the user input (e.g., 1310 a) moves the farther the user-movableaffordance (e.g., 1304 a) moves on the display.

In accordance with some embodiments, after (e.g., while) the set of oneor more conditions are being met, the electronic device detects an endof the user input (e.g., 1310 a, detecting a lift-off of the contact ofthe user input on the touch-sensitive surface). In response to detectingthe end of the user input, the electronic device updates display, on thedisplay, of the user-movable affordance (e.g., 1304 a at FIG. 13F) tothe first location on the display. Further in response to detecting theend of the user input, the electronic device transitions the electronicdevice to operate in the first state of ambient sound transparency(e.g., as illustrated by 1358 a and 1358 b of FIG. 13F). Further inresponse to detecting the end of the user input, the electronic devicetransitions production of audio using the audio source from the secondmode to the first mode (e.g., as illustrated by the change in locationof 1354 in FIGS. 13E-13F).

In accordance with some embodiments, after (e.g., while) the set of oneor more conditions are being met, the electronic device detects an endof the user input (e.g., detecting a lift-off of the contact of the userinput on the touch-sensitive surface). In response to detecting the endof the user input, the electronic device maintains display, on thedisplay, of the user-movable affordance at the second location on thedisplay. Further in response to detecting the end of the user input, theelectronic device maintains operation of the electronic device in thesecond state of ambient sound transparency. Further in response todetecting the end of the user input, the electronic device maintainsproduction of audio using the audio source in the second mode.

In accordance with some embodiments, the user input (e.g., 1310 a)includes a direction of movement. In accordance with some embodiments,the second state of ambient sound transparency (as illustrated by 1358 aand 1358 b in FIG. 13D) is based on the direction of movement of theuser input (e.g., 1310 a). For example, the electronic device selects aparticular speaker (e.g., 1358 b) to change the state of transparencybased on the direction of movement of the user input (e.g., 1310 a). Inaccordance with some embodiments, the second mode is based on thedirection of movement of the user input. For example, in the second modethe electronic device produces the audio such that the audio isperceived as being produced from a direction in space, the direction inspaced being based on the direction of movement of the first input(and/or based on the location of the user-moveable affordance 1304 a).

In accordance with some embodiments, the second mode is configured suchthat audio produced using the second mode is perceived by the user asbeing produced from a point in space that corresponds to the secondlocation of the displayed user-movable affordance.

In accordance with some embodiments, the first mode does not include amodification of an interaural time difference of audio. In someexamples, audio produced in the first mode is not modified using any ofan HRTF, cross cancellation, or interaural time difference.

In accordance with some embodiments, the second mode includes amodification of an interaural time difference of audio. In someexamples, the second mode includes a modification of an interaural timedifference of audio such that the audio is perceived by a user as beingproduced from a direction originating at a location that corresponds toa location of the user-moveable affordance, such as the left or to theright of the display or user. In some examples, audio produced in thesecond mode is modified using one or more of an HRTF, crosscancellation, and interaural time difference. Modifying an interauraltime difference of audio enables the user to perceive the audio ascoming from a particular direction. This directional information in theaudio provides the user with additional feedback about the placement ofdifferent content. Providing improved audio feedback to the userenhances the operability of the device and makes the user-deviceinterface more efficient (e.g., by helping the user to provide properinputs) which, additionally, reduces power usage and improves batterylife of the device by enabling the user to use the device more quicklyand efficiently.

In accordance with some embodiments, modification of the interaural timedifference of audio includes: combining a first channel audio (e.g., aright channel) of the audio and a second channel audio (e.g., a leftchannel) of the audio to form a combined channel audio, updating thesecond channel audio to include the combined channel audio at a firstdelay (e.g., Oms delay, less than a delay amount), and updating thefirst channel audio to include the combined channel audio at a seconddelay (e.g., a 100 ms delay, more than the delay amount) different fromthe first delay. In some examples, modifying the interaural timedifference of audio includes introducing a time delay to a first channelaudio (e.g., a right channel) without introducing a time delay to thesecond channel audio (e.g., a left channel) that is different from thefirst audio channel.

Note that details of the processes described above with respect tomethod 1400 (e.g., FIGS. 14A-14B) are also applicable in an analogousmanner to the methods described below and above. For example, methods700, 900, 1200, and 1500 optionally include one or more of thecharacteristics of the various methods described above with reference tomethod 1400. For example, the same or similar techniques are used toplace audio in space. For another example, the same audio sources may beused in the various techniques. For yet another example, currentlyplaying audio in each of the various methods can be manipulated usingthe techniques described in other methods. For brevity, these detailsare not repeated below.

FIG. 15 is a flow diagram illustrating a method for manipulatingmultiple audio streams of an audio source using an electronic device inaccordance with some embodiments. Method 1500 is performed at a device(e.g., 100, 300, 500, 1300) with a display and a touch-sensitivesurface. The electronic device is operably connected with two or morespeakers, including a first (e.g., left, 1358 a) speaker and a second(e.g., right, 1358 b) speaker. For examples, the two or more speakersare left and right speakers, left and right headphones, left and rightearphones, or left and right earbuds. Some operations in method 1500are, optionally, combined, the orders of some operations are,optionally, changed, and some operations are, optionally, omitted.

As described below, method 1500 provides an intuitive way formanipulating multiple audio streams of an audio source. The methodreduces the cognitive burden on a user for manipulating multiple audiostreams of an audio source, thereby creating a more efficienthuman-machine interface. For battery-operated computing devices,enabling a user to manipulate multiple audio streams of an audio sourcefaster and more efficiently conserves power and increases the timebetween battery charges.

The electronic device produces (1502), using the two or more speakers,audio (e.g., 1354 at FIG. 13F) using an audio source (e.g., audio file,music file, media file) in a first mode (e.g., a stereo mode, withoutapplying any of an HRTF, cross cancellation, or interaural timedifference). The audio source includes a plurality (e.g., five) of audiostreams, including a first audio stream and a second audio stream. Insome examples, each audio stream of the audio source is a stereo audiostream. In some examples, each audio stream is limited to a singlerespective instrument. In some examples, each audio stream is limited toa voice of a single respective singer. Thus, each audio stream of theaudio source is produced in the first mode.

The electronic device detects (1504), using the touch-sensitive surface,a first user input (e.g., 1310 b, a tap on an affordance, an input witha characteristic intensity that exceeds an intensity threshold).

In response (1506) to detecting the first user input (e.g., 1310 b), theelectronic device transitions (1508), using the two or more speakers,production of the first audio stream (e.g., 1354 a at FIG. 13H) of theaudio source from the first mode to a second mode that is different fromthe first mode.

Further in response (1506) to detecting the first user input (e.g., 1310b), the electronic device transitions (1510), using the two or morespeakers, production of the second audio stream (e.g., 1354 b at FIG.13H) of the audio source from the first mode to a third mode that isdifferent from the first mode and the second mode.

Placing the various audio streams at different locations in spaceenables the user to better distinguish between the different audiostreams. This, in turn, enables the user to more quickly and efficientlyturn off (and on) certain portions of the audio (e.g., a particularaudio stream) that the user wants to exclude from the listeningexperience. Providing improved audio feedback to the user enhances theoperability of the device and makes the user-device interface moreefficient (e.g., by helping the user to provide proper inputs andreducing user mistakes when operating/interacting with the device)which, additionally, reduces power usage and improves battery life ofthe device by enabling the user to use the device more quickly andefficiently.

Further in response (1506) to detecting the first user input (e.g., 1310b), the electronic device displays (1512), on the display, a firstvisual representation (e.g., 1306 a) of the first audio stream of theaudio source.

Further in response (1506) to detecting the first user input (e.g., 1310b), the electronic device displays (1514), on the display, a secondvisual representation (e.g., 1306 b) of the second audio stream of theaudio source, wherein the first visual representation (e.g., 1306 a) isdifferent from the second visual representation (e.g., 1306 b).

In accordance with some embodiments, blocks 1508-1514 occurconcurrently.

In accordance with some embodiments, the first mode does not include amodification of an interaural time difference of audio. In someexamples, audio produced in the first mode is not modified using any ofan HRTF, cross cancellation, or interaural time difference.

In accordance with some embodiments, the second mode includes amodification of an interaural time difference of audio. In someexamples, the second mode includes a modification of an interaural timedifference of audio such that the audio is perceived by a user as beingproduced from a direction originating at a location that corresponds toa location of the corresponding visual representation. In some examples,the second mode includes applying one or more of an HRTF, crosscancellation, and interaural time difference. In some examples, thethird mode includes a modification of an interaural time difference ofaudio. In some examples, the third mode includes applying one or more ofan HRTF, cross cancellation, and interaural time difference. Modifyingan interaural time difference of audio enables the user to perceive theaudio as coming from a particular direction. This directionalinformation in the audio provides the user with additional feedbackabout the placement of different content. Providing improved audiofeedback to the user enhances the operability of the device and makesthe user-device interface more efficient (e.g., by helping the user toprovide proper inputs) which, additionally, reduces power usage andimproves battery life of the device by enabling the user to use thedevice more quickly and efficiently.

In accordance with some embodiments, modification of the interaural timedifference of audio includes: combining a first channel audio (e.g., aright channel) of an audio stream and a second channel audio (e.g., aleft channel) of the audio stream to form a combined channel audio,updating the second channel audio to include the combined channel audioat a first delay (e.g., Oms delay, less than a delay amount), andupdating the first channel audio to include the combined channel audioat a second delay (e.g., a 100 ms delay, more than the delay amount)different from the first delay. In some examples, modifying theinteraural time difference of audio includes introducing a time delay toa first channel audio (e.g., a right channel) without introducing a timedelay to the second channel audio (e.g., a left channel) that isdifferent from the first audio channel.

In accordance with some embodiments, the electronic device displays, onthe display, the first visual representation (e.g., 1306 a) of the firstaudio stream of the audio source includes displaying the first visualrepresentation at a first location and sliding the first visualrepresentation in a first direction to a second location (e.g., 1306 aat FIG. 13I) on the display. In accordance with some embodiments, theelectronic device displays, on the display, the second visualrepresentation (e.g., 1306 b) of the second audio stream of the audiosource includes displaying the second visual representation at the firstlocation and sliding the second visual representation in a seconddirection different from the first direction to a third location (e.g.,1306 b at FIG. 13I) different from the second location.

In accordance with some embodiments, the electronic device detects,using the touch-sensitive surface, a second user input (e.g., 1310 c),the second input (e.g., 1310 c) starting at a location corresponding tothe second location and ending at a location corresponding to the firstlocation. In response to detecting the second user input, the electronicdevice slides the first visual representation from the second locationto the first location on the display while maintaining the second visualrepresentation at the third location on the display. Further in responseto detecting the second user input, the electronic device transitions,using the two or more speakers, production of audio using the firstaudio stream from the second mode to the first mode while maintainingproduction of audio using the second audio stream in the third mode.

In accordance with some embodiments, detecting the first user input(e.g., 1310 a) includes: accessing a characteristic intensity of thefirst user input, and determining that the characteristics intensity ofthe first user input exceeds an intensity threshold.

In accordance with some embodiments, while the electronic device isproducing, using the two or more speakers, audio using the first audiostream of the audio source and the second audio stream of the audiosource, the electronic device detects, using the touch-sensitivesurface, a third user input (e.g., 1310 d, a tap input) at a location onthe touch-sensitive surface corresponding to the first visualrepresentation (e.g., 1306 a). In response to detecting the third userinput (e.g., 1310 d), the electronic device ceases to produce, using thetwo or more speakers, audio (e.g., 1354 a) using the first audio streamof the audio source. Further in response to detecting the third userinput (e.g., 1310 d), the electronic device, the electronic devicemaintains, using the two or more speakers, production of audio using thesecond audio stream (e.g., 1354 b) of the audio source. Thus, theelectronic device detects a tap on an instrument affordance and disablesthe audio stream corresponding to that instrument.

In accordance with some embodiments, while the electronic device is notproducing, using the two or more speakers, audio using the first audiostream of the audio source and is producing, using the two or morespeakers, audio using the second audio stream of the audio source, theelectronic device detects, using the touch-sensitive surface, a fourthuser input (e.g., a tap input) at a location on the touch-sensitivesurface corresponding to the first visual representation. In response todetecting the fourth user input, the electronic device produces, usingthe two or more speakers, audio using the first audio stream of theaudio source. Further in response to detecting the fourth user input,the electronic device maintains, using the two or more speakers,production of audio using the second audio stream of the audio source.Thus, the electronic device detects a tap on an instrument affordanceand enables the audio stream corresponding to that instrument.

In accordance with some embodiments, the electronic device detects avolume control input (e.g., a user input requesting to turn down thevolume). In response to detecting the volume control input, theelectronic device modifies the volume of audio produced, using the twoor more speakers, for each audio stream in the plurality of audiostreams.

Note that details of the processes described above with respect tomethod 1500 (e.g., FIG. 15 ) are also applicable in an analogous mannerto the methods described above. For example, methods 700, 900, 1200, and1400 optionally include one or more of the characteristics of thevarious methods described above with reference to method 1500. Forexample, the same or similar techniques are used to place audio inspace. For another example, the same audio sources may be used in thevarious techniques. For yet another example, currently playing audio ineach of the various methods can be manipulated using the techniquesdescribed in other methods.

The foregoing description, for purpose of explanation, has beendescribed with reference to specific embodiments. However, theillustrative discussions above are not intended to be exhaustive or tolimit the invention to the precise forms disclosed. Many modificationsand variations are possible in view of the above teachings. Theembodiments were chosen and described in order to best explain theprinciples of the techniques and their practical applications. Othersskilled in the art are thereby enabled to best utilize the techniquesand various embodiments with various modifications as are suited to theparticular use contemplated.

Although the disclosure and examples have been fully described withreference to the accompanying drawings, it is to be noted that variouschanges and modifications will become apparent to those skilled in theart. Such changes and modifications are to be understood as beingincluded within the scope of the disclosure and examples as defined bythe claims.

As described above, one aspect of the present technology is thegathering and use of data available from various sources to improveaudio delivery. The present disclosure contemplates that in someinstances, this gathered data may include personal information data thatuniquely identifies or can be used to contact or locate a specificperson. Such personal information data can include demographic data,location-based data, telephone numbers, email addresses, twitter IDs,home addresses, data or records relating to a user's health or level offitness (e.g., vital signs measurements, medication information,exercise information), date of birth, or any other identifying orpersonal information.

The present disclosure recognizes that the use of such personalinformation data, in the present technology, can be used to the benefitof users. For example, the personal information data can be used todeliver an improved audio experience. Further, other uses for personalinformation data that benefit the user are also contemplated by thepresent disclosure. For instance, health and fitness data may be used toprovide insights into a user's general wellness, or may be used aspositive feedback to individuals using technology to pursue wellnessgoals.

The present disclosure contemplates that the entities responsible forthe collection, analysis, disclosure, transfer, storage, or other use ofsuch personal information data will comply with well-established privacypolicies and/or privacy practices. In particular, such entities shouldimplement and consistently use privacy policies and practices that aregenerally recognized as meeting or exceeding industry or governmentalrequirements for maintaining personal information data private andsecure. Such policies should be easily accessible by users, and shouldbe updated as the collection and/or use of data changes. Personalinformation from users should be collected for legitimate and reasonableuses of the entity and not shared or sold outside of those legitimateuses. Further, such collection/sharing should occur after receiving theinformed consent of the users. Additionally, such entities shouldconsider taking any needed steps for safeguarding and securing access tosuch personal information data and ensuring that others with access tothe personal information data adhere to their privacy policies andprocedures. Further, such entities can subject themselves to evaluationby third parties to certify their adherence to widely accepted privacypolicies and practices. In addition, policies and practices should beadapted for the particular types of personal information data beingcollected and/or accessed and adapted to applicable laws and standards,including jurisdiction-specific considerations. For instance, in the US,collection of or access to certain health data may be governed byfederal and/or state laws, such as the Health Insurance Portability andAccountability Act (HIPAA); whereas health data in other countries maybe subject to other regulations and policies and should be handledaccordingly. Hence different privacy practices should be maintained fordifferent personal data types in each country.

Despite the foregoing, the present disclosure also contemplatesembodiments in which users selectively block the use of, or access to,personal information data. That is, the present disclosure contemplatesthat hardware and/or software elements can be provided to prevent orblock access to such personal information data. For example, in the caseof audio delivery services, the present technology can be configured toallow users to select to “opt in” or “opt out” of participation in thecollection of personal information data during registration for servicesor anytime thereafter. In yet another example, users can select to limitthe length of time location information data is collected or maintained.In addition to providing “opt in” and “opt out” options, the presentdisclosure contemplates providing notifications relating to the accessor use of personal information. For instance, a user may be notifiedupon downloading an app that their personal information data will beaccessed and then reminded again just before personal information datais accessed by the app.

Moreover, it is the intent of the present disclosure that personalinformation data should be managed and handled in a way to minimizerisks of unintentional or unauthorized access or use. Risk can beminimized by limiting the collection of data and deleting data once itis no longer needed. In addition, and when applicable, including incertain health related applications, data de-identification can be usedto protect a user's privacy. De-identification may be facilitated, whenappropriate, by removing specific identifiers (e.g., date of birth,etc.), controlling the amount or specificity of data stored (e.g.,collecting location data a city level rather than at an address level),controlling how data is stored (e.g., aggregating data across users),and/or other methods.

Therefore, although the present disclosure broadly covers use ofpersonal information data to implement one or more various disclosedembodiments, the present disclosure also contemplates that the variousembodiments can also be implemented without the need for accessing suchpersonal information data. That is, the various embodiments of thepresent technology are not rendered inoperable due to the lack of all ora portion of such personal information data. For example, audio can bedelivered to users based on non-personal information data or a bareminimum amount of personal information, such as the content beingrequested by the device associated with a user, other non-personalinformation available to the system, or publicly available information.
